Multivariate regression analysis: model 2 (sex, follow-up duration, BMI, and ASA score)

Outcome	N*	β†	95% CI	P-value
Postoperative ASES score	96	0.69	0.11 to 1.27	0.019
Postoperative VAS pain score	96	–0.08	–0.14 to –0.01	0.028
Postoperative SST	96	0.07	–0.01 to 0.15	0.090
Postoperative FE (°)	101	0.05	–0.51 to 0.62	0.851
Postoperative ER (°)	99	–0.30	–0.71 to 0.11	0.155
Postoperative IR (°)	97	0.07	–0.02 to 0.17	0.130

BMI: body mass index, ASA: American Society of Anesthesiologists, CI: confidence interval, ASES: American Shoulder and Elbow Surgeons, VAS: visual analog scale, SST: Simple Shoulder Test, FE: forward elevation, ER: external rotation, IR: internal rotation.

^*N may be lower than overall cohort as patients with missing datapoint(s) were excluded from the model;

^†β represents the change in the respective measurement.
