ROC curve when using FL test and other characteristics for diagnosis NAFLD. We used AUROC to examine the use of the FL test as an indicator for diagnosis of NAFLD. The AUROC was 0.79 (95% CI: 0.758–0.827, p < 0.001), higher than the other predictors. When the FL test was >–0.425, the sensitivity, specificity, +LR, and –LR to predict patients with NAFLD were 74.72%, 72.12%, 2.68, and 0.35 respectively.

AUROC, area under the receiver operating characteristic; FL, fatty liver; LR, likelihood ratio; NAFLD, nonalcoholic fatty liver disease; ROC, receiver operating characteristic.
