The association between occupational physical activity and lifestyle factors and liver fibrosis. A generalized additive model was used to estimate the odds ratios and 95% confidence intervals, adjusted for age, sex, body mass index, job seniority, marriage, and average monthly earnings. OPA, occupational physical activity; drinking, drinking alcohol; diet, diet habits; NFS, non-alcoholic fatty liver disease fibrosis score; FIB-4, fibrosis index based on the four factors; APRI, aspartate aminotransferase to platelet ratio index; AAR, aspartate aminotransferase to alanine aminotransferase ratio; RPR, red blood cell distribution width to platelet. *P < 0.05.
