TGFB1 and metabolic dysfunction-associated steatohepatitis: Serum TGF-β1 was significantly correlated to serum ferritin considering the full population (r = 0.23, P = 0.009, Figure 2), especially in female patients (r = 0.5, P < 0.001), in NASH female patients (r = 0.45, P = 0.048) and in FL patients of both gender (r = 0.35, P = 0.02), whereas in all the CHC patients there was only a certain trend (r = 0.32, P = 0.05).
