OPA, occupational physical activity; drinking, drinking alcohol; NFS, non-alcoholic fatty liver disease fibrosis score.

Mediator M is a non-alcoholic fatty liver disease fibrosis score, Y means the dependent variable, and W represents the moderator. The results were adjusted for age, sex, body mass index, and job seniority.
