Note. A&T-I = Alive & Thrive-intensive; A&T-NI = Alive & Thrive-nonintensive; CI = confidence interval; EBF = exclusive breastfeeding. Bootstrapping (with 10 000 replications) linear regression models at the commune level regressed EBF prevalence in rounds 2–5 on exposure to the television spots, adjusted for EBF prevalence at baseline. We defined EBF as feeding breastmilk exclusively in the previous 24 h (i.e., no foods or liquids except medications such as drops or syrups).
