|Intestinal infection||59||48||0.80 (0.54–1.19)|
|Other infectionb||64||73||1·13 (0·81–1·58)|
CI, confidence interval; HIV/AIDS, human immunodeficiency virus/acquired immunodeficiency syndrome; RR, rate ratio.
a Calculated, as the mortality rate in the vitamin A arm divided by that in the placebo arm, after adjusting for clustering by use of random-effects models. The data come from an intention-to-treat analysis.
