^aRisk differences calculated at the cluster-level, all (crude and adjusted) adjusted for community-pair, and weighted according to the number of observations per village
^bAdjusted risk differences generated on the basis of expected number of events from a logistic regression model on individual data with independent variables including age, marital status and EA-level summary baseline measure of outcome indicator
^±Baseline measure controlled for: disclosed past year IPV and got helpful response
