FAP and steatosis: The statistical analysis demonstrated that the best predictive model for steatosis diagnosis should include the four variables with the following equation: -38.81 + 0.05 * LDL + 3.21 * CDH2 + 3.89 * FAP achieving a diagnostic performance with AUC of 0.91 (95% CI 0.75–0.97), with a sensitivity of 100% and specificity of 84% at a cut-off value determined at > 0.37 (Fig. 4A).
