Data are presented as median with interquartile range or number of patients (%). NRS: Numerical rating scale. The statistical significance was accepted with P values less than 0.05 for primary comparison among groups and 0.0083 for post-hoc multiple comparisons between pairwise groups (Bonferroni adjustment; 0.05/6). ^*P < 0.0083 compared to Group C.
