a
Separate models were estimated for each independent variable; β [95% CL] reflects bivariate association between variable and outcome.
b
Adjusted for child age, sex, birth order, prenatal iron + folic acid supplementation, ethnicity, caste, paternal literacy, maternal literacy, maternal age, and maternal Raven’s score.
c
Per cent of total variance accounted for by household wealth variable alone.
