Note: Data expressed as median (Q1–Q3). P-values refer to the difference between intervention and control groups in delta SF-36, i.e. change from baseline to follow-up (Mann–Whitney U Test). PCS = physical component summary, MCS = mental component summary

*p < 0.05 regarding group difference at baseline (Mann–Whitney U Test)

^† p < 0.05 regarding change from baseline to follow-up within groups (Wilcoxon matched pairs test)
