Table 3.

Comparisons of WSP outcome and impact indicators between baseline and follow-up. The analysis includes the number of sites (n), the percentage of sites reporting any given activity, median values across all sites at baseline and follow-up, and the statistical significance of the change between baseline and follow-up (p-value). p-values were determined using the paired Wilcox rank-sum test for all except the binary W3a and W3c indicators, which were determined using the chi-squared test. Results for each indicator, except O1b, are reported for 12-month periods.
