Costs Table 6.2 presents the mean costs in the two groups and the unadjusted differences in mean costs between groups. The costs of the In Balance intervention were estimated at €252 per person. From the societal perspective, mean costs in the intervention group were €6,170, compared to €10,265 in the control group. For all cost categories, with exception of the intervention costs and medication costs, mean costs in the intervention group were lower than in the control group. However, none of the cost differences reached statistical significance.
