Table 4. ROC analysis for single markers and indices discriminatory abilities regarding T2DM presence.

Predictors	AUC (95% CI)	SE	Sensitivity (%)	Specificity (%)	Cut-off	P
Receiver operating characteristic (ROC) curve analysis was performed to assess the discriminatory ability of the markers and indices. Abbreviations: AUC, area under the receiver operating characteristic curve; CI, confidence interval; GA, glycated albumin; HbA1c, glycated hemoglobin; HDL-C, high-density lipoprotein cholesterol; SE, standard error.
GA (%)	0.855 (0.788–0.922)	0.034	80.33	76.19	15.2	< 0.001
HbA1c (%)	0.966 (0.938–0.993)	0.014	91.80	90.48	5.5	< 0.001
GA/HDL-C	0.859 (0.785–0.915)	0.035	72.13	92.06	14.52	< 0.001
HbA1c/HDL-C	0.883 (0.813–0.943)	0.030	85.25	80.95	4.74	< 0.001
