⁺All of the study variables in this table are presented in median (IQR) unless otherwise specified

^*p-value is obtained by performing a Mann-Whitney U test comparing between the two groups at a specific time interval (baseline, post-operative week 2 or post-operative week 6)

^#Pain score and numbness score are components of the QuickDASH questionnaire ranging from 1 to 5, where 1 represents none, 2 represents mild, 3 represents moderate, 4 represents severe and 5 represents extreme
