  1. astatistically significant
  2. Note: Multivariate logistic regression model predicting key IYCFP knowledge and practices using intervention exposure: whether the mother saw a TV commercial or heard a radio spot promoting key IYCFP messages from the behavior change communication. Each indicator estimate is derived from a multivariate analysis 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
