Table 1 Methodological quality assessment criterion

From: Group-based physical activity interventions for postpartum women with children aged 0–5 years old: a systematic review of randomized controlled trials

Criterion

Description

A

Key baseline characteristics are presented separately for treatment groups (age, and one relevant outcome) and for randomised controlled trials, positive if baseline outcomes were statistically tested and results of tests were provided

B

Randomisation procedure clearly and explicitly described and adequately carried out in randomized controlled trials (generation of allocation sequence, allocation concealment and implementation)

C

Validated measures of outcomes assessed (validation in same age group reported and/or cited)

D

Drop out reported and ≤ 20% for < 6-month follow-up or ≤ 30% for ≥ 6-month follow-up

E

Blinded outcome variable assessments

F

Outcomes assessed a minimum of 6-months after pre-test

G

Intention to treat analysis for outcome(s) (participants analysed in group they were originally allocated to, and participants not excluded from analyses because of non-compliance to treatment or because of some missing data)

H

Potential confounders accounted for in outcome analysis (e.g., baseline score, group/cluster, age)

I

Summary results for each group + treatment effect (difference between groups) + its precision (e.g., 95% confidence interval)

J

Power calculation reported, and the study was adequately powered to detect hypothesized relationships
