Association of Serum Creatinine Level with Prognosis of Laparotomy for Acute Mesenteric Ischemia after Cardiovascular Surgery

Figure 1

Receiver operating characteristic curves for the serum creatinine level (bold solid line) and the P-POSSUM-predicted mortality rate (bold dotted line). The area under the curve (AUC) of the serum creatinine level for in-hospital mortality is 0.813 (95% confidence interval [CI]: 0.646–0.979,  = 0.004) and that of P-POSSUM is 0.687 (95% CI: 0.483–0.892,  = 0.087). The optimal cutoff value of the serum creatinine level was 1.59 mg/dL with a sensitivity of 0.846 and a specificity of 0.687 to predict in-hospital mortality.
