Final multivariable model in the total study population of associations between musculoskeletal pain during the preceding 12 months in the neck, shoulders, hands, lower back and feet, and self-reported physical workload, psychosocial, personal, and lifestyle factors. These were calculated using Poisson regression (backward selection). P-values (overall in categorical variables), prevalence ratio (PR) and 95 % confidence intervals (CI) are shown.The variables job support, leadership, self-efficacy, domestic work, training and smoking habits did not qualify for the final model in any body region
