Key: SF-36-PCS physical component summary, SF-36-MCS mental component summary. Continuous variables are expressed as the mean and standard deviation (SD). Independent-sample Student’s t tests were used for group comparisons. Bold p values indicate significant differences
^aThe SF-36 range is 0–100, where 100 indicates a high HRQoL
^bThe SF-6D range is 0–1, where 1 indicates a high HRQoL
^cThe 15D range is 0–1, where 1 indicates a high HRQoL
