Table 4 Effect of multidisciplinary team-intervention compared with brief intervention in the new study group.

From: Subgroup analyses on return to work in sick-listed employees with low back pain in a randomised trial comparing brief and multidisciplinary intervention

  HRR (95% CI) P of interaction n
No moderator* 1.14 (0.74-1.76)   120
Work-related models**    
Job satisfaction, high 0.72 (0.38-1.38) 0.14 49
Job satisfaction, low 1.41 (0.77-2.57)   69
Influence on work planning 0.95 (0.58-1.54) 0.48 80
No influence on work planning 1.49 (0.57-3.93)   37
Health and work-related models**    
At risk of losing job because of current sick leave 1.95 (0.78-4.88) 0.10 34
Not at risk of losing job because of current sick leave 0.95 (0.57-1.59)   82
Worried about losing job 1.84 (0.93-3.64) 0.11 50
Not worried about losing job 0.87 (0.49-1.54)   67
Permanently impaired work ability 1.40 (0.82-2.38) 0.47 71
Not permanently injured 0.93 (0.41-2.11)   42
  1. *HRR was calculated in the multivariable model without the interaction term
  2. **Adjusted for gender.
  3. HRR (HRmultidisciplinary group/HRbrief intervention) was calculated for each level of the independent variable.
