	Number	Number of cases	One year cumulative incidence	Odds ratio model 1*	Model 2†	Model 3‡	Model 4¶	Model 5§
Odds ratios are computed from one year cumulative incidence and adjusted stepwise for potential confounders. *Adjusted for age. †Adjusted for age and job strain (mechanical exposure) or mechanical exposure (psychological demands, decision latitude, job support, and job strain). ‡Adjusted for age and job strain (mechanical exposure) or mechanical exposure (psychological demands, decision latitude, job support, and job strain), marital status, and country of origin. ¶Adjusted for age and job strain (mechanical exposure) or mechanical exposure (psychological demands, decision latitude, job support, and job strain), marital status, country of origin, and educational level. §Adjusted for age and job strain (mechanical exposure) or mechanical exposure (psychological demands, decision latitude, job support, and job strain), marital status, country of origin, educational level, and pain from other regions.
