Figure 3. Receiver operating characteristic (ROC) curve analysis of the diagnostic performance of surrogate indexes of visceral adiposity and BMI for the presence or absence of hepatic steatosis.

Figure 3

All ROC curves were statistically significant with P<0.001. The best area under de ROC curve was that of waist circumference (0.935±SE 0.027) which was better than those of WHR (difference 0.08, 95% confidence interval 0.01–0.16), VAI (difference 0.18, 95% confidence interval 0.10–0.26 and MOAD (difference 0.17, 95% confidence interval 0.08–0.26), but was not different than that of BMI (difference 0.02, 95% confidence interval −0.01 – to 0.05, P = 0.155). Similarly, the area under the ROC curve of BMI was better compared with those of VAI (difference 0.16, 95% confidence interval 0.08–0.24, P<0.001) and MOAD (difference 0.15, 95% confidence interval 0.04–0.26, P = 0.007) but was not different than that of WHR (difference 0.06, 95% confidence interval 0.03 – to 0.15, P = 0.176).
