  1. aPrevalences are adjusted for non-response by age and sex. Region and district estimates are additionally weighted by commune size. 95% Confidence Intervals (95%CIs) are logit-transformed confidence limits. Where prevalence is zero, one-sided 97.5% Clopper-Pearson exact CIs are presented
  2. bRural commune (communities over-sampled by halving the sampling interval)
  3. cUrban commune (communities under-sampled by doubling the sampling interval)
