Demographic and parasitological characteristics of subjects at baseline.

NOTE: CI, confidence interval. epg �C eggs per gram of faeces (from duplicate Kato-Katz); values were log transformed and the geometric mean is presented. M, male F, female.*The numbers of infants contributing to intensity determination was lower than for prevalence since the latter was based on Kato Katz plus stool sedimentation whereas intensity was based on Kato Katz alone.

备注：CI即置信区间（confidence interval）。epg指每克粪便虫卵数（eggs per gram of faeces，源自重复Kato-Katz检测），相关数值已进行对数转换，报告结果为几何均数。M代表男性，F代表女性。
* 用于感染强度确定的婴儿样本量低于患病率统计的样本量，这是因为患病率的统计基于Kato-Katz法联合粪便沉淀法，而感染强度仅以Kato-Katz法为计算依据。
