The efficacy of sampling strategies for estimating scabies prevalence
Fig 6
Observed scabies prevalence in samples selected using. different (a) assignment methods and (B) sampling percentages.
The results (median and 2.5% to 97.5% quantiles) are plotted for an exemplar input prevalence percentage between 20–30% across all population sizes with a sampling percentage between 20–30%. Red dashed lines represent 20% and 30% prevalence. Additional results with differing input prevalence and differing population sizes are presented in S2, S3 and S4 Figs. In panel B, the highest sampling percentages could not be achieved in the school-based sampling strategy due to insufficient population size in the school aged group.
