Outcome measures for the patients participating in the different rehabilitation periods. Mean values at baseline and follow-up regarding return to work (RTW, %), occupational competence (OSA), personal control (Mastery), and sense of coherence (SoC). Paired t-test, Hedges’ g effect size (ES); with magnitude high (H), medium (M) or small (S) (n = 106).
