  1. n* denotes the total number of child observations analyzed in follow-up rounds.
  2. aPrevalence ratio (PR), 95% Confidence Interval (95% CI) and p value derived from log-binomial generalized estimating equations with robust standard errors to account for clustering within village. Model conditions group assignment, age in months, sex, and diarrhoea outcome.
  3. bPR, 95% CI and p-value derived from log-binomial generalized estimating equations with robust standard errors to account for clustering within village. Model further adjusts for government-defined socio-economic status.
