Preoperative opiate prescription, days	1.73 (1.14–2.61)	0.009	1.97 (1.16–3.36)	0.013

Multivariable logistic regression models were performed for number of preoperative opiate prescriptions, days of preoperative opiate prescriptions, and number of providers prescribing opiate prescriptions preoperatively. These variables were modeled separately, and additional models are provided in Supplementary Tables S1, S2, S3.
