OPA, occupational physical activity; RPR, red blood cell distribution width to the platelet.
Mediator M is red blood cell distribution width to platelet, Y means dependent variable, and W represents the moderator. The results were adjusted for age, sex, body mass index, and job seniority.
*P < 0.05.
