ROC curves for PLT and serum AFP levels, alone and in combination, to predict liver fibrosis (LS type> 7 kPa)
The sensitivity, specificity, PPV, NPV, and AUC (95% CI and P-value) for PLT levels (0.460, 0.819, 86.8%, 33.7%, and 0.678 [0.611–0.746, P<0.001], respectively); for AFP levels (0.581, 0.873, 93.1%, 41.4%, and 0.755 [0.698–0.812, P<0.001], respectively); and for AFP and PLT in combination (0.682, 0.833, 92.3%, 47.2%, and 0.819 [95% CI: 0.768–0.870, P<0.001], respectively) were determined.
