It is important to highlight that miR-34a had a higher diagnostic power and sensitivity for NASH (AUC: 0.81, sensitivity: 0.70, specificity: 0.86) than other already known biomarkers, such as ALT (AUC: 0.68, sensitivity: 0.84, specificity: 0.94), CK-18-M30 and CK-18-M60 (M30 AUC: 0.70, sensitivity: 0.41, specificity: 0.94; M60 AUC: 0.72, sensitivity: 0.52, specificity: 0.94). Here, KRT18 is linked to metabolic dysfunction-associated steatohepatitis.
