Figure 1: ROC curve to determine the diagnostic utility of Cystatin-C, creatinine, and uric acid in PE. Cystatin-C showed the superior diagnostic accuracy compared to the other two traditional renal markers. From the curve, we determined the cut-off value for Cystatin-C with maximum sensitivity and specificity to be 0.9. Similarly, for creatinine, the cut-off was taken as 0.38 and for uric acid 4.25, respectively.
