Summary table.

This table summarizes the results of our study in terms of false positive rate and power. A ‘++’ implies a very good performance, a ‘+’ a good performance, a ‘−’ a bad performance and a ‘.’ that it was not possible to assess a comparable power given that the false positive rate was not correct. FP: False positive rate.本表格总结了本研究在假阳性率（False Positive Rate）与检验效能两方面的研究结果。其中，符号‘++’代表性能极佳，‘+’代表性能良好，‘−’代表性能欠佳，而符号‘.’则表示因假阳性率不符合规范，无法评估具有可比性的检验效能。FP为假阳性率（False Positive Rate）的缩写。
