Table 4

Logistic regression analyses of prognostic variables for RTW after one year.

Prognostic variables	Model 1	Model 2	Model 3	Model 4
	OR (95% CI)	OR (95% CI)	OR (95% CI)	OR (95%)
Low decision authority	0.982 (0.970–0.999)	0.987 (0.971–1.004)	0.986 (0.971–1.002)	0.990 (0.975–1.007)
Bullying	0.715 (0.513–0.994)	0.677 (0.474–0.966)	0.634 (0.426–0.926)	0.731 (0.513–1.040)
Work ability index	1.220 (1.038–1.434)	1.285 (1.074–1.537)	1.356 (1.113–1.612)	1.235 (1.029–1.401)
Full-time sick leave at baseline	0.431 (0.222–0.830)	0.430 (0.223–0.830)	0.454 (0.234–0.880)	0.511 (0.251–1.010)

In models 1–3, the prognostic variable was analyzed separately with adjustment for the following.
Model 1: age, gender, marital status, and occupational position.
Model 2: model 1 and global symptom index.
Model 3: model 2 and life events.
Model 4: all four prognostic variables forced into the model adjusted for age, gender, occupational position, global symptom index, marital status, and life event last year.
