Comparison of fatty liver index with noninvasive methods for steatosis detection and quantification

Figure 4 Receiver operating characteristic curves for diagnostic accuracy of fatty liver index vs SteatoTest or hepatorenal ultrasound index. A: SteatoTest; B: Hepatorenal ultrasound index (HRI). Comparing fatty liver index (FLI) to SteatoTest ≥ S2, area under the receiver operating characteristic curve (AUROC) was 0.97 (95% CI: 0.95-0.98). Comparing FLI to HRI ≥ 1.5, AUROC was 0.82 (95% CI: 0.77-0.87). Receiver operating characteristic curve of sensitivity (true-positive fraction) plotted against 1- specificity (false-positive fraction) of the FLI for diagnosis of steatosis.
