Adjusted mean differences estimated from mixed effects models with random intercept; 95% confidence limits were calculated using robust variance estimates.
Model 1 adjusted for maternal age, work and marital status, household SES score, hygiene index score, community of residence, infant sex and age, and duration and severity of diarrheal episode. Model 2 adjusted for all variables included in model 1 and Raven’s scores, years of schooling, and maternal academic skills scores.
