Association Between Serum Afamin Levels with Nonalcoholic Associated Fatty Liver Disease

Figure 2

Receiver operating characteristic (ROC) analysis for the diagnosis of NAFLD. The ROC curves for afamin, BMI, and afamin plus the BMI are shown. The area under the curve (AUC) of afamin was 0.746, and the positive predictive value was 62.5%. The negative predictive value was 69.3%, and the accuracy was 65.9%. The area under the curve (AUC) of the BMI was 0.818, and the positive predictive value was 77.3%. The negative predictive value was 70.5%, and the accuracy was 73.9%. The area under the curve (AUC) of afamin plus the BMI was 0.878, and the positive predictive value was 77.3%. The negative predictive value was 79.5%, and the accuracy was 78.4%.
