aData are shown as n (%) unless otherwise indicated. Bolded P values indicate statistically significant between-group differences (P < .05). ASES, American Shoulder and Elbow Surgeons; BMI, body mass index; MCS, Mental Component Summary; SANE, Single Assessment Numeric Evaluation; VR-12, Veterans RAND 12-Item Health Survey.
bThe VR-12 is norm-based at 50, whereas the ASES and SANE are on a scale of 0-100. Higher scores for all of these variables are favorable.
