Increased urinary adiponectin level is associated with contrast-induced nephropathy in patients undergoing elective percutaneous coronary intervention

Table 3 AUC of variables for predicting CIN

Variables	AUC	95%CI	P value
UAPN	0.7204	0.582–0.859	P < 0.01
UAPN≥12.24^a	0.7257	0.614–0.837	P < 0.01
Scr ≥ 124	0.6498	0.537–0.763	P < 0.01
UAPN≥12.24 plus Scr ≥ 124^b	0.7509	0.626–0.876	P < 0.01

^aUAPN ≥ 12.24 and Scr ≥ 124 have the same performance in predicting CIN(P = 0.18)
^bAdding UAPN≥12.24 to Scr ≥ 124 could provide a better predictive value than Scr ≥ 124 alone (P = 0.04). AUC Area under the curve, UAPN Urinary adiponectin, Scr Serum creatinine, CIN Contrast-induced nephropathy
