Radar plots representing HRQoL on the 8 domains of the SF-36 in the study population compared with the Dutch norm (gray line). A HRQoL on SF-36 domains for the total cohort at 3, 6, and 12 months. B–D HRQoL on SF-36 domains for participants with no (red line), partial (orange line), or full (green) return to work. In B, the results are shown for 3-months follow-up; in C, for 6-months follow-up; and in D, for 12-months follow-up. * Significant improvement over time (p < 0.007).  = significant difference in HRQoL between no return to work and partial/full return to work (p < 0.05).   = significant difference between no/partial return to work and full return to work (p < 0.03). PF, physical functioning; RP, role limitations due to physical health; RE, role limitations due to emotional problems; VT, vitality; MH, mental health; SF, social functioning; BP, bodily pain; GH, general health
