ALDH18A1 and Hepatic fibrosis: We found FIB4 and GPR to be significantly associated with liver fibrosis in fully adjusted models, taking into account multiple testing correction (Fig. 2): FIB4 showed statistical differences between F2 and F3 group (p = 0.018) or F3 and F4 group (p = 0.032), respectively; GPR showed statistical differences between F2 and F3 group (p = 0.013) or F3 and F4 group (p = 0.015), respectively.
