  1. aResponse scale was 1 to 5, with 5 meaning “strongly agree” and 1 meaning “strongly disagree”. This table reflects the percent of respondents who “agreed” and “strongly agreed”.
  2. b P value from t-test at baseline or at endline.
  3. cInteraction term P value from multivariate logistic regression models of each result on intervention status, time point, and interaction of these two variables, while controlling for provider cadre and ZDF branch and accounting for clustering of responses within each facility.
  4. dThe dash means that the Odds Ratio coefficient for the interaction term = 1, thus no P value is associated with it.
  5. ART, Antiretroviral therapy; PMTCT, Prevention of mother-to-child transmission of HIV.
