Note: all values are expressed as mean ± SD. Score improvement within each group is represented by . T1: baseline; T2: 12 weeks after baseline; PMR: progressive muscle relaxation; QOL-PCS: quality of life-physical component summary score; QOL-MCS: quality of life-mental component summary score. ^*Paired-sample -test value for T1 versus T2 within each group; ^a compared with in the control group.
