1 Bayesian credibility interval. 2 Child’s age, sex, breastfeeding status at baseline, baseline HAZ and length of follow-included in pathway. 3 Indirect effects represent pathogen-specific transmission pathways leading to children’s exposure to enteric infections and growth impairment. Indirect effects calculated by multiplying coefficients for paths a × b in Figure 1.
