Index test:

Sensitivity, specificity, positive predictive value, negative predictive value, accuracy

目标人群(可以是某种疾病患者或正常人群,详细描述其疾病特征,注意应纳入符合分布特点的全序列病例,具有良好的代表性)

pillcam胶囊内镜检查结果发现小肠病变的患者。

例数:

Sample size:

300

Target condition (The target condition is a particular disease or disease stage that the index test will be intended to identify. Please specify the characteristics in detail; the population should has a complete spectrum and good representative):

Patients with small bowel diseases diagnosed by capsule endoscopy.

容易混淆的疾病人群(即与目标疾病不易区分的一种或多种不同疾病,应避免采用正常人群对照的病例-对照设计):
