^aAdjusted differences and robust SE were calculated from generalized estimating equations with LAZ or WLZ scores as the outcomes and covariates that included each episode plus maternal education, age, height, CD4 counts at baseline, parity, and infant low-birth weight, sex, age, and HIV status as a time-varying covariate.

^bThe occurrence of at least one episode was assessed during the month prior to each anthropometric measurement.

^cCough + other was defined as cough with at least one of the following events: difficulty breathing, chest retractions and refusal to eat, drink, or breastfeed.
