aEach triangle represents one study.
▲ = Favours the intervention, 95% CI excludes 0; △ = Unclear effect potentially favouring the intervention, 95% CI includes zero; ▼ = Favours the control, 95% CI excludes 0; ▽ = Unclear effect potentially favouring the control, 95% CI includes 0. (+): low overall risk of bias; (?): unclear overall risk of bias; (‐): high overall risk of bias.
DID: difference in differences; HAZ: height‐for‐age z‐score; n: number; pp: percentage point; SD: standard deviation; SE: standard error; WAZ: weight‐for‐age z‐score; WHZ: weight‐for‐height z‐score.
