aThe majority of loss to follow-ups were inability to trace at later follow-ups for funding and other reasons. 21 infants died during the original BFPH study and 12 during the original CIGNIS study. We have no information about later deaths. 18 infants in the CIGNIS study were HIV-positive and thus excluded from the analysis
bBirth weights of CIGNIS children were taken from Road-to-Health cards
