Background
Gestational weight gain is positively associated with fetal growth, and observational studies of food supplementation in pregnancy have reported increases in gestational weight gain and ...fetal growth.
Objectives
To assess the effects of education during pregnancy to increase energy and protein intake, or of actual energy and protein supplementation, on energy and protein intake, and the effect on maternal and infant health outcomes.
Search methods
We searched the Cochrane Pregnancy and Childbirth Group's Trials Register (31 January 2015), reference lists of retrieved studies and contacted researchers in the field.
Selection criteria
Randomised controlled trials of dietary education to increase energy and protein intake, or of actual energy and protein supplementation, during pregnancy.
Data collection and analysis
Two review authors independently assessed trials for inclusion and assessed risk of bias. Two review authors independently extracted data and checked for accuracy. Extracted data were supplemented by additional information from the trialists we contacted.
Main results
We examined 149 reports corresponding to 65 trials. Of these trials, 17 were included, 46 were excluded, and two are ongoing. Overall, 17 trials involving 9030 women were included. For this update, we assessed methodological quality of the included trials using the standard Cochrane criteria (risk of bias) and the GRADE approach. The overall risk of bias was unclear.
Nutritional education (five trials, 1090 women)
Women given nutritional education had a lower relative risk of having a preterm birth (two trials, 449 women) (risk ratio (RR) 0.46, 95% CI 0.21 to 0.98, low‐quality evidence), and low birthweight (one trial, 300 women) (RR 0.04, 95% CI 0.01 to 0.14). Head circumference at birth was increased in one trial (389 women) (mean difference (MD) 0.99 cm, 95% CI 0.43 to 1.55), while birthweight was significantly increased among undernourished women in two trials (320 women) (MD 489.76 g, 95% CI 427.93 to 551.59, low‐quality evidence), but did not significantly increase for adequately nourished women (MD 15.00, 95% CI ‐76.30 to 106.30, one trial, 406 women). Protein intake increased significantly (three trials, 632 women) (protein intake: MD +6.99 g/day, 95% CI 3.02 to 10.97). No significant differences were observed on any other outcomes such as neonatal death (RR 1.28, 95% CI 0.35 to 4.72, one trial, 448 women, low‐quality evidence), stillbirth (RR 0.37, 95% CI 0.07 to 1.90, one trial, 431 women, low‐quality evidence), small‐for‐gestational age (RR 0.97, 95% CI 0.45 to 2.11, one trial, 404 women, low‐quality evidence) and total gestational weight gain (MD ‐0.41, 95% CI ‐4.41 to 3.59, two trials, 233 women). There were no data on perinatal death.
Balanced energy and protein supplementation (12 trials, 6705 women)
Risk of stillbirth was significantly reduced for women given balanced energy and protein supplementation (RR 0.60, 95% CI 0.39 to 0.94, five trials, 3408 women, moderate‐quality evidence), and the mean birthweight was significantly increased (random‐effects MD +40.96 g, 95% CI 4.66 to 77.26, Tau² = 1744, I² = 44%, 11 trials, 5385 women, moderate‐quality evidence). There was also a significant reduction in the risk of small‐for‐gestational age (RR 0.79, 95% CI 0.69 to 0.90, I² = 16%, seven trials, 4408 women, moderate‐quality evidence). No significant effect was detected for preterm birth (RR 0.96, 95% CI 0.80 to 1.16, five trials, 3384 women, moderate‐quality evidence) or neonatal death (RR 0.68, 95% CI 0.43 to 1.07, five trials, 3381 women, low‐quality evidence). Weekly gestational weight gain was not significantly increased (MD 18.63, 95% CI ‐1.81 to 39.07, nine trials, 2391 women, very low quality evidence). There were no data reported on perinatal death and low birthweight.
High‐protein supplementation (one trial, 1051 women)
High‐protein supplementation (one trial, 505 women), was associated with a significantly increased risk of small‐for‐gestational age babies (RR 1.58, 95% CI 1.03 to 2.41, moderate‐quality evidence). There was no significant effect for stillbirth (RR 0.81, 95% CI 0.31 to 2.15, one trial, 529 women), neonatal death (RR 2.78, 95% CI 0.75 to 10.36, one trial, 529 women), preterm birth (RR 1.14, 95% CI 0.83 to 1.56, one trial, 505 women), birthweight (MD ‐73.00, 95% CI ‐171.26 to 25.26, one trial, 504 women) and weekly gestational weight gain (MD 4.50, 95% CI ‐33.55 to 42.55, one trial, 486 women, low‐quality evidence). No data were reported on perinatal death.
Isocaloric protein supplementation (two trials, 184 women)
Isocaloric protein supplementation (two trials, 184 women) had no significant effect on birthweight (MD 108.25, 95% CI ‐220.89 to 437.40) and weekly gestational weight gain (MD 110.45, 95% CI ‐82.87 to 303.76, very low‐quality evidence). No data reported on perinatal mortality, stillbirth, neonatal death, small‐for‐gestational age, and preterm birth.
Authors' conclusions
This review provides encouraging evidence that antenatal nutritional education with the aim of increasing energy and protein intake in the general obstetric population appears to be effective in reducing the risk of preterm birth, low birthweight, increasing head circumference at birth, increasing birthweight among undernourished women, and increasing protein intake. There was no evidence of benefit or adverse effect for any other outcome reported.
Balanced energy and protein supplementation seems to improve fetal growth, and may reduce the risk of stillbirth and infants born small‐for‐gestational age. High‐protein supplementation does not seem to be beneficial and may be harmful to the fetus. Balanced‐protein supplementation alone had no significant effects on perinatal outcomes.
The results of this review should be interpreted with caution. The risk of bias was either unclear or high for at least one category examined in several of the included trials, and the quality of the evidence was low for several important outcomes. Also, as the anthropometric characteristics of the general obstetric population is changing, those developing interventions aimed at altering energy and protein intake should ensure that only those women likely to benefit are included. Large, well‐designed randomised trials are needed to assess the effects of increasing energy and protein intake during pregnancy in women whose intake is below recommended levels.
Rising prevalence of childhood obesity and type 2 diabetes mellitus (T2DM) is an emerging public health issue.
To investigate the association of maternal hyperglycemia exposure during pregnancy with ...obesity and abnormal glucose tolerance in offspring, and the age at occurrence.
We searched MEDLINE and EMBASE for observational studies on obesity and diabetes in offspring of diabetic mothers (gestational diabetes mellitus (GDM), type 1 diabetes mellitus (T1DM) and T2DM), and those on non-diabetic mothers. We performed fixed effect meta-analysis for all studies except when heterogeneity was detected. The quality of studies was evaluated using the Risk of Bias Assessment Tool for Nonrandomized Studies (RoBANS).
Twenty observational studies were included involving a total of 26,509 children. Offspring of GDM mother had higher BMI z-score in childhood (pooled MD: 0.14, 95%CI: 0.04-0.24, seven studies, 21,691children, low quality of evidence). Offspring of T1DM mothers had higher BMI z-score from prepubertal to adolescent (pooled MD: 0.35, 95% CI: 0.13-0.58, three studies, 844 children, low quality of evidence) compared with control. After adjustment for maternal pre-pregnancy BMI, this association remained in offspring of T1DM, but disappeared in those of GDM mothers. Offspring of GDM mother had higher 2-hour plasma glucose from prepubertal to early adulthood (pooled MD: 0.43 mmol/L, 95% CI: 0.18-0.69, five studies, 890 children), while those of T1DM mothers had higher rate of T2DM in 2-5 years old to early adulthood (pooled odds ratio OR, 6.10: 95% CI: 1.23-30.37, two studies, 448 children, very low quality of evidence) compared with control. As there was only one study with offspring of T2DM mothers, evidence is sparse.
Only observational studies were included, with a few adequately adjusted for covariables.
Exposure to maternal hyperglycemia was associated with offspring obesity and abnormal glucose tolerance especially in offspring of T1DM mothers, but the evidence relies on observational studies with low quality of evidence only.

Vitamin A (VA) supplementation reduces the risk of developing bronchopulmonary dysplasia (BPD). However, a previous meta-analysis showed that VA had minimal efficacy for preventing BPD in very low ...birth weight infants (VLBWIs).
To elucidate the effects of VA supplementation for BPD prevention in extremely low birth weight infants (ELBWIs).
This systematic review and meta-analysis followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. We registered the protocol on PROSPERO, the international prospective registry of systematic reviews (registration number: CRD42016050887). We searched the following five databases: CINAHL, CENTRAL, EMBASE, MEDLINE, and PubMed; screened the reference lists of retrieved articles to identify randomized controlled trials (RCTs); and assessed the Cochrane Risk of Bias for each study. The certainty of the evidence was assessed using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) guidelines.
Four studies (total, 1,011 infants) were included. VA was administered intramuscularly in 3 studies and orally in 1 study. VA supplementation for ELBWIs had benefited oxygen dependency at the postmenstrual age of 36 weeks in survivors (pooled risk ratio, 0.88; 95% confidence intervals (CI), 0.77-0.99; 4 trials, 841 infants, moderate certainty of evidence), which is similar to the meta-analysis in VLBWIs. Length of hospital stay was reduced in the VA group (mean difference, -49.9; 95% CI, -88.78 to -11.02; 1 trial, 20 infants, low certainty of evidence). The meta-analysis showed no reduction in the risk of neonatal death, oxygen use at 28 days in survivors, duration of mechanical ventilation, intraventricular hemorrhage, retinopathy in prematurity, and necrotizing enterocolitis.
VA supplementation for ELBWIs is potentially effective in decreasing oxygen dependency at the postmenstrual age of 36 weeks.

Anemia is a leading cause of maternal deaths and adverse pregnancy outcomes in developing countries.
We conducted a systematic review and meta-analysis to estimate the pooled prevalence of anemia, ...the association between maternal anemia and pregnancy outcomes, and the population-attributable fraction (PAF) of these outcomes that are due to anemia in low- and middle-income countries.
PubMed, EMBASE, CINAHL, and the British Nursing Index were searched from inception to May 2015 to identify cohort studies of the association between maternal anemia and pregnancy outcomes. The anemic group was defined as having hemoglobin concentrations <10 or <11 g/dL or hematocrit values <33% or <34% depending on the study. A metaregression and stratified analysis were performed to assess the effects of study and participant characteristics on adverse pregnancy risk. The pooled prevalence of anemia in pregnant women by region and country-income category was calculated with the use of a random-effects meta-analysis.
Of 8182 articles reviewed, 29 studies were included in the systematic review, and 26 studies were included in the meta-analysis. Overall, 42.7% (95% CI: 37.0%, 48.4%) of women experienced anemia during pregnancy in low- and middle-income countries. There were significantly higher risks of low birth weight (RR: 1.31; 95% CI: 1.13, 1.51), preterm birth (RR: 1.63; 95% CI: 1.33, 2.01), perinatal mortality (RR: 1.51; 95% CI: 1.30, 1.76), and neonatal mortality (RR: 2.72; 95% CI: 1.19, 6.25) in pregnant women with anemia. South Asian, African, and low-income countries had a higher pooled anemia prevalence than did other Asian and upper-middle-income countries. Overall, in low- and middle-income countries, 12% of low birth weight, 19% of preterm births, and 18% of perinatal mortality were attributable to maternal anemia. The proportion of adverse pregnancy outcomes attributable to anemia was higher in low-income countries and in the South Asian region.
Maternal anemia remains a significant health problem in low- and middle-income countries.

Pre-eclampsia has an immense adverse impact on maternal and perinatal health especially in low- and middle-income settings. We aimed to estimate the associations between pre-eclampsia/eclampsia and ...its risk factors, and adverse maternal and perinatal outcomes.
We performed a secondary analysis of the WHO Global Survey on Maternal and Perinatal Health. The survey was a multi-country, facility-based cross-sectional study. A global sample consisting of 24 countries from three regions and 373 health facilities was obtained via a stratified multi-stage cluster sampling design. Maternal and offspring data were extracted from records using standardized questionnaires. Multi-level logistic regression modelling was conducted with random effects at the individual, facility and country levels.
Data for 276,388 mothers and their infants was analysed. The prevalence of pre-eclampsia/eclampsia in the study population was 10,754 (4%). At the individual level, sociodemographic characteristics of maternal age ≥30 years and low educational attainment were significantly associated with higher risk of pre-eclampsia/eclampsia. As for clinical and obstetric variables, high body mass index (BMI), nulliparity (AOR: 2.04; 95%CI 1.92-2.16), absence of antenatal care (AOR: 1.41; 95%CI 1.26-1.57), chronic hypertension (AOR: 7.75; 95%CI 6.77-8.87), gestational diabetes (AOR: 2.00; 95%CI 1.63-2.45), cardiac or renal disease (AOR: 2.38; 95%CI 1.86-3.05), pyelonephritis or urinary tract infection (AOR: 1.13; 95%CI 1.03-1.24) and severe anemia (AOR: 2.98; 95%CI 2.47-3.61) were found to be significant risk factors, while having >8 visits of antenatal care was protective (AOR: 0.90; 95%CI 0.83-0.98). Pre-eclampsia/eclampsia was found to be a significant risk factor for maternal death, perinatal death, preterm birth and low birthweight.
Chronic hypertension, obesity and severe anemia were the highest risk factors of preeclampsia/eclampsia. Implementation of effective interventions prioritizing risk factors, provision of quality health services during pre-pregnancy and during pregnancy for joint efforts in the areas of maternal health are recommended.

Background
Three classes of inhaler medications are used to manage chronic obstructive pulmonary disease (COPD): long‐acting beta‐agonists (LABA), long‐acting muscarinic antagonists (LAMA), and ...inhaled corticosteroids (ICS). When two classes of medications are required, LAMA plus LABA (LAMA+LABA) and LABA plus ICS (LABA+ICS) are often selected because these combinations can be administered via a single medication device. The previous Global Initiative for Chronic Obstructive Lung Disease (GOLD) guidance recommended LABA+ICS as the first‐line treatment for managing stable COPD in high‐risk people of categories C and D. However, the updated GOLD 2017 guidance recommends LAMA+LABA over LABA+ICS.
Objectives
To compare the benefits and harms of LAMA+LABA versus LABA+ICS for treatment of people with stable COPD.
Search methods
We performed an electronic search of the Cochrane Airways Group Specialised Register (2 February 2016), ClinicalTrials.gov (4 June 2016), and the World Health Organization Clinical Trials Search Portal (4 June 2016), followed by a handsearch (5 June 2016). Two review authors screened and scrutinised the selected articles.
Selection criteria
We included individual randomised controlled trials, parallel‐group trials, and cross‐over trials comparing LAMA+LABA and LABA+ICS for stable COPD. The minimum accepted trial duration was one month and trials should have been conducted in an outpatient setting.
Data collection and analysis
Two review authors independently extracted data and evaluated risk of bias. We resolved any discrepancies through discussion. We analysed dichotomous data as odds ratios (OR), and continuous data as mean differences (MD), with 95% confidence interval (CI) using Review Manager 5. Exacerbations were measured by counting the number of people experiencing one or more exacerbation.
Main results
We included 11 studies comprising 9839 participants in our quantitative analysis. Most studies included people with moderate to severe COPD, without recent exacerbations. One pharmaceutical sponsored trial that included only people with recent exacerbations was the largest study and accounted for 37% of participants. All but one study were sponsored by pharmaceutical companies, thus we rated them as having a high risk of 'other bias'. The unsponsored study was at high risk of performance and detection bias, and possible selective reporting.
Five studies recruited GOLD Category B participants, one study recruited Category D participants, two studies recruited Category A/B participants, and three studies recruited participants regardless of category. Follow‐up ranged from 6 to 52 weeks.
Compared to the LABA+ICS arm, the results for the pooled primary outcomes for the LAMA+LABA arm were as follows: exacerbations, OR 0.82 (95% CI 0.70 to 0.96, P = 0.01, I2 = 17%, low quality evidence); serious adverse events (SAE), OR 0.91 (95% CI 0.79 to 1.05, P = 0.18, I2 = 0, moderate quality evidence); St. George's Respiratory Questionnaire (SGRQ) total score change from the baseline, MD ‐1.22 (95% CI ‐2.52 to 0.07, P = 0.06, I2 = 71%, low quality evidence); and trough forced expiratory volume in one second (FEV1) change from the baseline, MD 0.08 L (95% CI 0.06 to 0.09, P < 0.0001, I2 = 50%, moderate quality evidence). Compared to the LABA+ICS arm, the results for the pooled secondary outcomes for the LAMA+LABA arm were as follows: pneumonia, OR 0.57 (95% CI 0.42 to 0.79, P = 0.0006, I2 = 0%, low quality evidence); all‐cause death, OR 1.01 (95% CI 0.61 to 1.67, P = 0.88, I2 = 0%, low quality evidence); and SGRQ total score change from the baseline of 4 points or greater (the minimal clinically important difference for the SGRQ is 4 points), OR 1.25 (95% CI 1.09 to 1.44, P = 0.002, I2 = 0%, moderate quality evidence).
Authors' conclusions
For the treatment of COPD, LAMA+LABA has fewer exacerbations, a larger improvement of FEV1, a lower risk of pneumonia, and more frequent improvement in quality of life as measured by an increase over 4 units or more of the SGRQ. These data were supported by low or moderate quality evidence generated from mainly participants with moderate to severe COPD in heterogeneous trials with an observation period of less than one year. Our findings support the recently updated GOLD guidance.
Abstract Background Partner education during pregnancy may be able to prevent postnatal mental health problems, and support expectant fathers in their transition to parenthood. The aim of this ...systematic review is to investigate the effects of prenatal childbirth education among partners of pregnant women, particularly regarding paternal postnatal mental health and couple relationship. Methods We searched Medline, CINAHL, EMBASE, PsycINFO, ERIC, and CENTRAL using terms such as “partners of pregnant women,” “education,” and “prenatal support.” Searches were limited to randomized trials. Results We included 11 trials out of 13 reports that addressed the following topics: childbirth preparation, couple relationship, infants and parenting, postpartum psychosocial issues, and housework sharing. Overall risk of bias was low or unclear. Study outcomes, including parents’ mental health (e.g., anxiety, depression, distress), couple relationship, parents’ transition adjustment and parenting stress, and parents’ satisfaction with their experience of childbirth and prenatal childbirth education programs were reported. Limitations The studies included in this review were very diverse regarding intervention intensity and content, outcome types, measurement tools, and outcome timing. This impeded evaluation of the interventions’ effectiveness. Conclusion No sufficient evidence was identified that prenatal childbirth education for partners of pregnant women protects against paternal postnatal depression and couple relationship; however, paternal postnatal mental health is important to maternal and perinatal healthcare. The results of this review suggest that further research and intervention are required to provide partners of pregnant women with evidence-based information and support whole families during the perinatal period.

The poor coverage of essential maternal services, such as antenatal care (ANC) and skilled delivery care utilization, accounts for higher maternal and infant mortality in low- and middle-income ...countries (LMICs). Although mobile health (mHealth) interventions could potentially improve the service utilization in resource-limited settings, their effectiveness remains unclear.
This review aimed to summarize the effect of mHealth interventions on improving the uptake of ANC visits, skilled birth attendance at the time of delivery, and facility delivery among pregnant women in LMICs.
We conducted a comprehensive search on 9 electronic databases and other resources from inception to October 2020. We included individual randomized controlled trials and cluster randomized controlled trials that assessed the effectiveness of mHealth interventions for improving perinatal health care utilization among healthy pregnant women in LMICs. We performed a random-effects meta-analysis and estimated the pooled effect size by using risk ratios (RRs) with 95% CIs. In addition, 2 reviewers independently assessed the risk of bias of the included studies by using the Cochrane risk of bias tool and the certainty of the evidence by using the Grading of Recommendation, Assessment, Development and Evaluation approach.
A total of 9 studies (10 articles) that randomized 10,348 pregnant women (n=6254, 60.44% in the intervention group; n=4094, 39.56% in the control group) were included in this synthesis. The pooled estimates showed a positive effect of mHealth interventions on improving 4 or more ANC visit utilizations among pregnant women in LMICs, irrespective of the direction of interventions (1-way communications: RR 2.14, 95% CI 1.76-2.60, I
=36%, 2 studies, moderate certainty; 2-way communications: RR 1.17, 95% CI 1.08-1.27, I
=59%, 3 studies, low certainty). Only 2-way mHealth interventions were effective in improving the use of skilled birth attendance during delivery (RR 1.23, 95% CI 1.14-1.33, I
=0%, 2 studies, moderate certainty), but the effects were unclear for 1-way mHealth interventions (RR 1.04, 95% CI 0.97-1.10, I
=73%, 3 studies, very low certainty) when compared with standard care. For facility delivery, the interventions were effective in settings where fewer pregnant women used facility delivery (RR 1.68, 95% CI 1.30-2.19, I
=36%, 2 studies, moderate certainty); however, the effects were unclear in settings where most pregnant women already used facility delivery (RR 1.01, 95% CI 0.97-1.04, I
=0%, 1 study, low certainty).
mHealth interventions may contribute to improving ANC and skilled delivery care utilization among pregnant women in LMICs. However, more studies are required to improve their reproducibility and efficiency or strengthen the evidence of different forms of mHealth interventions because of the considerable heterogeneity observed in the meta-analyses.

Background
Repetitive peripheral magnetic stimulation (rPMS) is a non‐invasive treatment method that can penetrate to deeper structures with painless stimulation to improve motor function in people ...with physical impairment due to brain or nerve disorders. rPMS for people after stroke has proved to be a feasible approach to improving activities of daily living and functional ability. However, the effectiveness and safety of this intervention for people after stroke currently remain uncertain. This is an update of the review published in 2017.
Objectives
To assess the effects of rPMS in improving activities of daily living and functional ability in people after stroke.
Search methods
On 7 January 2019, we searched the Cochrane Stroke Group Trials Register; the Cochrane Central Register of Controlled Trials (CENTRAL), in the Cochrane Library; MEDLINE; Embase; the Cumulative Index to Nursing and Allied Health Literature (CINAHL); PsycINFO; the Allied and Complementary Medicine Database (AMED); Occupational Therapy Systematic Evaluation of Evidence (OTseeker); the Physiotherapy Evidence Database (PEDro); ICHUSHI Web; and six ongoing trial registries. We screened reference lists, and we contacted experts in the field. We placed no restrictions on the language or date of publication when searching electronic databases.
Selection criteria
We included randomised controlled trials (RCTs) conducted to assess the therapeutic effect of rPMS for people after stroke. Comparisons eligible for inclusion were (1) active rPMS only compared with 'sham' rPMS (a very weak form of stimulation or a sound only); (2) active rPMS only compared with no intervention; (3) active rPMS plus rehabilitation compared with sham rPMS plus rehabilitation; and (4) active rPMS plus rehabilitation compared with rehabilitation only.
Data collection and analysis
Two review authors independently assessed studies for inclusion. The same review authors assessed methods and risk of bias, undertook data extraction, and used the GRADE approach to assess the quality of evidence. We contacted trial authors to request unpublished information if necessary. We resolved all disagreements through discussion.
Main results
We included four trials (three RCTs and one cross‐over trial) involving 139 participants. Blinding of participants and physicians was well reported within all trials. We judged the overall risk of bias across trials as low. Only two trials (with 63 and 18 participants, respectively) provided sufficient information to be included in the meta‐analysis. We found no clear effect of rPMS on activities of daily living at the end of treatment (mean difference (MD) ‐3.00, 95% confidence interval (CI) ‐16.35 to 10.35; P = 0.66; 1 trial; 63 participants; low‐quality evidence) and at the end of follow‐up (MD ‐2.00, 95% CI ‐14.86 to 10.86; P = 0.76; 1 trial; 63 participants; low‐quality evidence) when comparing rPMS plus rehabilitation versus sham plus rehabilitation. We found no statistical difference in improvement of upper limb function at the end of treatment (MD 2.00, 95% CI ‐4.91 to 8.91; P = 0.57; 1 trial; 63 participants; low‐quality evidence) and at the end of follow‐up (MD 4.00, 95% CI ‐2.92 to 10.92; P = 0.26; 1 trial; 63 participants; low‐quality evidence) when comparing rPMS plus rehabilitation versus sham plus rehabilitation. We observed a significant decrease in spasticity of the elbow at the end of follow‐up (MD ‐0.48, 95% CI ‐0.93 to ‐0.03; P = 0.03; 1 trial; 63 participants; low‐quality evidence) when comparing rPMS plus rehabilitation versus sham plus rehabilitation. In terms of muscle strength, rPMS treatment was not associated with improved muscle strength of the ankle dorsiflexors at the end of treatment (MD 3.00, 95% CI ‐2.44 to 8.44; P = 0.28; 1 trial; 18 participants; low‐quality evidence) when compared with sham rPMS. No studies provided information on lower limb function or adverse events, including death. Based on the GRADE approach, we judged the quality of evidence related to the primary outcome as low, owing to the small sample size of the studies.
Authors' conclusions
Available trials provided insufficient evidence to permit any conclusions about routine use of rPMS for people after stroke. Additional trials with large sample sizes are needed to provide robust evidence for rPMS after stroke.
Abstract Background Resistance training (RT) is a core component of cardiac rehabilitation. We investigated the effects of RT on exercise capacity, muscle strength, and mobility in middle-aged and ...elderly patients with coronary artery disease (CAD). Methods We searched for randomized controlled trials of RT versus usual care, or combined RT and aerobic training (AT) versus AT alone, and identified 440 trials in total from inception to January 2014. Participants who had myocardial infarction, coronary revascularization, angina pectoris or CAD were included in the analysis. Those who had heart failure, heart transplants with either cardiac resynchronization therapy or implantable defibrillators were excluded. Results Twenty-two trials totaling 1095 participants were analyzed. We performed random-effects meta-analysis. In middle-aged participants, RT increased lower extremity muscle strength standardized mean difference (SMD): 0.65, 95% confidence interval (CI): 0.35 to 0.95, upper extremity muscle strength (SMD: 0.73, 95% CI: 0.48 to 0.99) and peak oxygen consumption (VO2 ) weight mean difference (WMD): 0.92 mL/kg/min, 95% CI: 0.12 to 1.72, but did not improve mobility compared with the control. In elderly participants, RT increased lower extremity muscle strength (SMD: 0.63, 95% CI: 0.05 to 1.21), upper extremity muscle strength (SMD: 1.18, 95% CI: 0.56 to 1.80), and peak VO2 (WMD: 0.70 mL/kg/min, 95% CI: 0.03 to 1.37), and improved mobility (SMD: 0.61, 95% CI: 0.21 to 1.01) compared with the control. Conclusions Resistance training could increase exercise capacity and muscle strength in middle-aged and elderly patients, and mobility in elderly patients, with CAD.
