ROC-curves of the Chinese NAFLD score to predict NAFLD in the estimation group, the internal Chinese validation group and the Finnish external validation group.

<p>In the estimation group, AUROC = 0.79 (0.77, 0.81),cut-off = -0.79, Specificity = 0.72, Sensitivity = 0.71. In the internal Chinese validation group, AUROC = 0.76 (0.73, 0.78), cut-off = -0.79, Specificity = 0.71, Sensitivity = 0.69. In the Finnish external validation group, AUROC = 0.74 (0.69, 0.80), cut-off = 0.68, Specificity = 0.62, Sensitivity = 0.79.</p
