Moderated mediation model of household enteric pathogen transmission pathways and HAZ at 60-day follow-up among 551 children 12–23 months of age in the MSD cohort in Kolkata, India.

1 Bayesian credibility interval. 2 Child’s age, sex, breastfeeding status at baseline, baseline HAZ and length of follow-up 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 2D.
