  1. Utilization rates (%) of interventions, mean intervention costs2 per person and the difference in mean costs (€, 2006 values1) between the intervention and usual care groups during the 12-months follow-up period. 1 € = US $ 1.27; 2 prices according to the professional organisation (Occupational Health Service - Arbo Unie); 3 Since there is no variation in intervention costs within the groups, SDs and 95% confidence intervals can not be calculated.
