Statistics
Differences in QALYs between the two groups were estimated using the trapezoidal method (area under the curve).Cost-effectiveness (CE) plane of the incremental cost-effectiveness ratios of multimodal occupational therapy (intervention group) in addition to usual care (control group) were recalculated with 1000 replications of the study data using the bootstrap resampling method. The intervention is at the origin. QALYs, quality-adjusted life-years.Cost-effectiveness acceptability curve for direct costs, representing the probability that the multimodal intervention is cost-effective in addition to usual care. At a willingness-to-pay threshold of €27 500/QALY, the probability of multimodal intervention being cost-effective was 94.5%. QALYs, quality-adjusted life-years.Between-group differences in mean costs and mean effects were analysed using independent sample t-test. Significance level was set to 0.05. Statistical analyses were performed using Excel, SPSS V.26 and Stata V.16.
