  1. 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; C: Validated measures of outcomes assessed; 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); H: Potential confounders accounted for in outcome analysis; 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
