Forest plot for Outcome 3: non-cephalic presentation at birth. Mantel-Haenszel test included 78 centers and 1761 participants. Fixed-effects (1): logistic regression with fixed center effect and fixed treatment effect, included 71 centers and 1739 participants. Logistic regression with fixed center effect and fixed treatment-by-center interaction, both weighted (Fixed-effects (2)) and un-weighted by center size (Fixed-effects (3)), included 57 centers and 1649 participants. Random-effects (1): logistic regression with random center effect and fixed treatment effect, Random-effects (2): logistic regression with random center effect and random treatment-by-center interaction, and GEE used all 81 centers and 1764 participants. CI, confidence interval, GEE, generalized estimating equations, OR, odds ratio.
