Abstract
Existing methods used to rank the value of individual screening markers in screening programmes are inadequate. We have developed a simple Screening Marker Index: (Screening Marker Index = Positive Predictive Value x Sensitivity). The Screening Marker Index proved to be superior to existing indices in ranking screening markers according to their ability to identify the conditions sought.
摘要
现有的用于对筛查项目中个体筛查标志物的价值进行排名的方法是不充分的。我们开发了一种简单的筛查标志物指数：（筛查标志物指数=阳性预测值 x 敏感度）。根据筛查标志物识别目标疾病的能力，筛查标志物指数在对筛查标志物进行排序方面优于现有的指数。
