Area under the curve, 95% confidence interval and standard error for the parameters of selected parameters’ discriminatory ability regarding Fatty Liver Index level (low vs. higher risk); pairwise comparison of the areas under ROC curves (AUCs) for model and separate parameters

Parameter	AUC	95% CI	SE	Sensitivity (%)	Specificity (%)	Cut-off value (%)	P-value*
Model (4 parameters)	0.990	0.977–1.003	0.007	–	–	–	< 0.001
Bioavailable testosterone	0.868	0.803–0.933	0.033	96	55	27.65	< 0.001
Log HOMA-IR	0.850	0.783–0.917	0.034	96	45	1.43	< 0.001
Log hsCRP	0.758	0.676–0.840	0.042	96	53	–0.14	< 0.001
RBP4	0.729	0.639–0.819	0.046	96	94	26.50	< 0.001

AUC – area under ROC curve, CI – confidence interval, SE – standard error, Model: Bioavailable testosterone, Log HOMA-IR – logarithmically transformed homeostasis model assessment of insulin resistance, Log hsCRP – logarithmically transformed high sensitivity C-reactive protein, RBP4 – retinol-binding protein 4.
