Prevalence of any infection and moderate-to-heavy intensity infections before and after quality control on fecal egg counts.

The prevalence of each soil-transmitted helminth in each study site was calculated based on the duplicate Kato-Katz results at baseline using both the original dataset (Pre-QC FEC dataset) as well as that dataset after adjusting for discrepancies detected during quality control (QC) on the fecal egg counts (Post-QC FEC dataset). The infection intensity in both datasets was classified into light and moderate-to-heavy intensity (MHI) according to the thresholds set by the World Health Organization [10]. Values that differ between both datasets are highlighted in bold font.本研究基于各研究基线处的重复加藤-克茨（Kato-Katz）检测结果，分别采用原始数据集（Pre-QC FEC数据集，即质控前粪便虫卵计数数据集）与经粪便虫卵计数质量控制（QC）环节检出偏差校正后的数据集（Post-QC FEC数据集，即质控后粪便虫卵计数数据集），计算各研究地点中每一种土源性蠕虫（soil-transmitted helminth）的感染率。两类数据集内的感染强度均参照世界卫生组织制定的判定阈值，划分为轻度感染与中重度感染（MHI）两类。两类数据集间存在差异的数值将以粗体字体标注。
