Postmatching Receiver Operating Characteristic Curve Analysis of NT‐proBNP, eGFR, and hs‐CRP for the Prediction of CRS1

	AUC	P Value	95% CI
eGFR at admission, mL/(min·1.73 m2)	0.843	<0.001	0.792 to 0.894
NT‐proBNP at admission, pg/mL	0.719	<0.001	0.654 to 0.784
hs‐CRP at admission, mg/L	0.656	<0.001	0.587 to 0.725
NT‐proBNP+eGFR+hs‐CRP	0.863	<0.001	0.816 to 0.910

The differences in the AUC values between the individual biomarkers and their combinations were statistically significant, with P values of 0.0372 (eGFR vs NT‐proBNP+eGFR+hs‐CRP), <0.0001 (NT‐proBNP vs NT‐proBNP+eGFR+hs‐CRP), and <0.0001 (hs‐CRP vs NT‐proBNP+eGFR+hs‐CRP). AUC indicates area under the receiver operating characteristic curve; CI, confidence interval; CRS1, cardiorenal syndrome type 1; eGFR, estimated glomerular filtration rate; hs‐CRP, high‐sensitivity C‐reactive protein; NT‐proBNP, amino‐terminal pro–brain natriuretic peptide.
