  1. astatistically significant
  2. Note: Multivariate logistic regression model predicting key IYCF knowledge and practices using intervention exposure: whether the mother saw any TV commercial or heard any radio spot from the ASTUTE intervention (not just those specific to nutrition). Each indicator estimate is derived from a multivariate logistic regression model that estimates the probability of the health indicator given exposure to the intervention. All model estimates control for maternal age, maternal education level, and wealth index. The “No Exposure” group refers to those who did not report any interpersonal communication (IPC) or media exposure
