(B) Risk for shoulder-neck pain in relation to mechanical and psychosocial exposure among occupationally active women between 45 and 64 years old in the Malmö shoulder and neck study
| Number | Number of cases | One year cumulative incidence | Odds ratio (95%CI)model 1* | Odds ratio (95%CI)model 2† | Odds ratio (95%CI)model 3‡ | Odds ratio (95%CI)model 4¶ | |
|---|---|---|---|---|---|---|---|
| Odds ratios are computed from one year cumulative incidence for the different combinations of mechanical exposure and job strain to test for effect modification, and adjusted stepwise for potential confounders. *Adjusted for age. †Adjusted for age, marital status, and country of origin. ‡Adjusted for age, marital status, country of origin, and educational level. ¶Adjusted for age, marital status, country of origin, educational level, and pain from other regions. | |||||||
