Dependent variables at one-year
aPredictors: (constant), age, sex, hypertension, diabetes, depression
bPredictors: (constant), pain at one-year, age, sex, hypertension, diabetes, depression
Change in scores was calculated by subtracting scores at one-year follow-up visit from baseline scores
Function Model 1 predictors: age, sex, diabetes, hypertension, and depression.
Function Model 2 predictors: pain at one-year, age, sex, diabetes, hypertension, and depression
ASES: American Shoulder and Elbow Surgeons, SF-12: Short Form-12 survey, PCS: physical component summary, MCS: mental component summary, NS: nonsignificant.
