Table 4.

Sensitivities, specificities, and area under curve (AUC) values of the parameters in evaluating the degree of renal damage in CKD.

Group vs. Group	Parameter	AUC	95% CI	Cutoff value	Sensitivity (%)	Specificity (%)
Group A vs. Group B	cortex FF (%)	0.766	0.593 - 0.892	1.27	66.7	82.4
Group A vs. Group C	cortex R2* (/s)	0.788	0.630 - 0.901	15.87	88.9	68.2
Group B vs. Group C	cortex R2* (/s)	0.829	0.674 - 0.930	16.97	70.6	81.8

Group A, mild renal damage group; group B, moderate to severe renal damage group; group C, healthy control group; CI, confidence interval; AUC: area under curve; FF, fat fraction.
