Figure 4 (A) Violin plot of Visual Analog Scale (VAS) scores based on 107 patients followed up to 1 year postoperatively. Compared with the preoperative, patients had significantly lower VAS scores at all postoperative time periods. (t0 – pre-operation; t1 – one month; t2 – three months; t3 – six months; t4 – one year; *** P<0.001). (B) Violin plot of Pittsburgh Sleep Quality Index (PSQI) scores based on 107 patients followed up to 1 years postoperatively. Compared with preoperatively, patients had significantly lower PSQI scores at all postoperative time periods. (t0 – pre-operation; t1 – one month; t2 – three months; t3 – six months; t4 – one year; *** P<0.001, * P<0.05). (C) Violin plot of Disabilities of the Arm, Shoulder and Hand (DASH) scores based on 99 patients followed up to 1 years postoperatively. Compared with preoperatively, patients had significantly lower DASH scores at all postoperative time periods. (t0 – pre-operation; t1 – one month; t2 – three months; t3 – six months; t4 – one year; *** P<0.001).
