Fig. 3. ROC curve of the RI for diagnosing NDKD.

Fig. 3.

The AUC is 0.759 (P=0.001) and the RI has a sensitivity of 57.1% (95% CI, 28.9% to 82.3%) and specificity of 81.0% (95% CI, 58.1% to 94.6%) for diagnosing NDKD, using a cutoff value of ≤0.69. ROC, receiver operating characteristic; RI, resistive index; NDKD, non-diabetic kidney disease; AUC, area under the ROC curve; CI, confidence interval.
