  1. Estimates weighted to adjust for non-response/non-availability of data on STH infections; 95% CI calculated using Taylor linearization method to account for clustering within communities
  2. CI confidence interval, STH soil-transmitted helminths
  3. *p values were calculated using Cochran-Mantel-Haenszel statistics (based on table scores)
  4. **Arithmetic mean intensity calculated for those positive only
