Generalized linear model of the HIV-free survival at endline with a logit link, among 132 catchment areas (CAs). In addition to months since introduction of Option A, the model controlled for HIV-free survival at baseline and for the following CA-level population and facility characteristics: urban vs. rural catchment area, number of health staff members, number of village health workers/health promoters, number of days per week the facility is open for antenatal care, the proportion of health staff that received training on Option A, and whether the facility had on site CD4 testing at baseline.
