In model 1, PTX3, ALT, and age were independently associated with presence of fibrosis in NAFLD after adjustment for age, smoking status, systolic and diastolic blood pressure, uric acid, AST, ALT, ALP, GGT, ferritin, and hs-CRP (P = 0.032, P = 0.002, and P = 0.01, resp). Here, GPT is linked to fibrosis.
