Figure 3. Meta-analyses of 3 studies of biomarkers accuracy (Obuchowski measure: weighted area under the ROC curve [wAUROC]) for the diagnostic of liver injury in patients with severe obesity.

Figure 3

FibroTest for the diagnosis of advanced fibrosis (at least equivalent to METAVIR score F2). SteatoTest for the diagnosis of advanced steatosis (>30% steatosis). ActiTest for the diagnosis of NASH (NAS score >4). The horizontal lines indicate the 95% confidence interval for the mean difference between between test's wAUROCs and random (0.500). The vertical lines indicate the equivalence line (0% difference). Positive differences indicate a difference in favor of test). When the horizontal line crosses the vertical line, there is no significant difference. Ave = Average of AUROCs.
