Analysis restricted to intervention facilities only (n = 75); p-values in Column (5) were from t-test of the null hypothesis that the gap [Columns (2)–(4)] is equal to zero; p-values in Column (7) were for testing the null hypothesis of zero CI; SD, standard deviation; terciles for wealth status were generated with equal-size from intervention arm separately; Gap, least poor—poorest; ratio, least poor/poorest; the results were generally similar in Column (5) when non-parametric test (Wilcoxon rank-sum) is used (Supplementary Table S6).
