Prevalence of hookworm infection, sensitivity, specificity and negative predictive value using different diagnostic techniques.

N = 205, KK: Kato Katz technique, SNF sodium nitrate flotation.Prevalence of hookworm infection, sensitivity, specificity and negative predictive value using different diagnostic techniques.本数据集样本量N=205，涉及两种诊断技术：加藤厚涂片法（Kato Katz technique，简称KK）与硝酸钠浮聚法（sodium nitrate flotation，简称SNF），统计了不同诊断技术对应的钩虫感染患病率、灵敏度、特异度及阴性预测值。
