Variable	Crude OR (95% CI)	Adjusted OR (95% CI)*
Age	1.007 (0.99 to 1.02)	1.01 (0.99 to 1.03)
Preoperative Heart Rate	1.007 (0.99 to 1.02)	1.02 (1.008 to 1.04)
Preoperative Gait Speed	1.92 (0.80 to 4.72)	3.70 (1.21 to 11.26)
Postoperative Pain	1.02 (0.97 to 1.07)	1.01 (0.96 to 1.08)

OR: Odds ratio

^*Model was adjusted for gender (p=0.07), anesthesia technique (p=0.14), surgical risk (p=0.8), pre-operative mean arterial pressure (p=0.001), and co-morbidity status (p=0.02).

For a 0.1 unit change in gait speed, the OR of early discharge was 1.14 (1.02 to 1.27).

Surgical risk was categorized as major intervention vs. minor intervention.

Minor intervention was defined as all of the following: surgery duration <1h, expected blood loss <500 ml, and no opening of visceral cavity (except in case of diagnostic laparoscopic procedures).

Major intervention was defined as any of the following: duration of procedure ≥1h, expected blood loss ≥500 ml, opening of visceral cavity, potential massive respiratory or hemodynamic effects due to surgery.
