Quality of recovery (QoR-15) scores at 24, 48, and 72 h after surgery.

Time point	OFA (n = 98)	OA (n = 97)	Mean difference (95% CI)	P value
24 h†	110 ± 12	106 ± 15	4 (2 to 8)	0.002
48 h	113 ± 13	114 ± 16	−1 (−2 to 5)	0.334
72 h	121 ± 10	120 ± 13	1 (−1 to 4)	0.257

Values are presented as mean ± standard deviation (SD). † QoR-15 at 24. OFA, opioid-free anesthesia; OA, opioid-based anesthesia; QoR-15, 15-item Quality of Recovery questionnaire; CI, confidence interval; SD, standard deviation h was the prespecified primary endpoint.
