Fig. 4.
ROC analysis results of the urinary concentration of SNAG-Δ5-CA (A), SNAG-Δ5-CG (B), SNAG-Δ5-CT (C), S7B-Δ5-CA (D), S7O-Δ5-CA (E), and their total concentration (F). AUC, cut-off concentration, sensitivity, and specificity are also shown. The AUC values ranged between 0.916 and 1.0. The sensitivities were 92.6–100% and the specificities were 81.1–100%. The cut-off concentrations ranged from 15 to 800 ng/mg creatinine (Cr) and S7B-Δ5-CA showed clear-cut diagnostic performance.
