Objective To explore the solutions of problems with the ROC analysis for different types data.
Method Two kinds of ROC analyses of three cardiac infarction markers, cTNT, CK-MB mass and MYO, were performed with the ROC program developed by Yunnan Provincial Clinical Laboratory Center.
Results The distribution of prime data had a large range, which produced a bad analysis result. After logarithmic transformation, the prime data that had smaller range now can be analyzed with full-span method. The results were similar to the ROC analyzed with the overlapped data.
Conclusions We should choose different statistical method depend on the distribution of data when we performed ROC analyses.
