Cumulative effects of excess high-normal alanine aminotransferase levels in relation to new-onset metabolic dysfunction-associated fatty liver disease in China

Figure 3 Optimal alanine aminotransferase cut-off points for the diagnosis of metabolic dysfunction-associated fatty liver disease. The optimal alanine aminotransfer (ALT) cut-off point was 18.5 U/L based on receiver-operating characteristic curve and Youden index, and the cut-off point for high-normal ALT was 18.6-40 U/L. AUC: Area under the curve.
