Required sample sizes estimated from simulation results for the simple random, household, and school sampling methods to achieve a given precision, where input scabies prevalence is distributed according to the age-specific method.

Small, medium, and large population sizes represent ranges of [500, 1500], (1500, 2500], (2500, 4000]. For the scenarios with X’s in school sampling, sampling all school-aged children was insufficient to have 95% confidence that prevalence within the selected precision could be obtained.

小规模、中规模与大规模人群分别对应取值区间[500, 1500]、(1500, 2500]以及(2500, 4000]。针对学校抽样中标记为X的场景，仅对所有学龄儿童进行抽样，无法保证以95%的置信水平获得符合预设精度要求的患病率估计结果。(XLSX)
