^aDifference-in-differences: the difference in the proportion between the intervention and comparison areas at end-line subtracted by the difference in proportion between intervention and comparison areas at baseline
^bDenominator: Baseline (intervention = 159, comparison = 165); End-line (intervention = 205, comparison = 147)
^cDenominator: Baseline (intervention = 128, comparison = 94); End-line (intervention = 138, comparison = 141)
^dDenominator: Baseline (intervention = 270, comparison = 273); End-line (intervention = 354, comparison = 284)
^†P-value obtained from the logistic regression model for the difference-in-difference analysis (for the difference between intervention and comparison groups over time). P-value was adjusted for clustering and age
