aAdjusted for distance to nearest health facility, history of child death, polygyny, season of birth, gender of the newborn, twinship and for clustering.
bAdjusted for polygyny, maternal use of bednet, anthropometric z-scores at week-3 and for clustering.
cAdjusted for distance to nearest health facility, history of child death, polygyny, maternal use of bednet, season of birth, gender of the baby, twinship and for clustering.
Adjustment for clustering was done fitting a Cox Gamma shared frailty model in STATA/SE 11.0.
