Table 1. Surgical time and length of hospital stay based on surgeon experience.

Outcomes	Estimated mean (estimated standard error)		*MR (95%CI)	p-value
	In-training surgeons	Qualified surgeons
Length of hospital stay, days	2.22 (1.09)	1.89 (1.10)	0.85 (0.77–0.95)	0.005
Surgical time, min	211.51 (1.08)	169.13 (1.09)	0.80 (0.73–0.88)	<0.001

^*MR is the ratio between the mean surgical time and the length of hospitalization with qualified or in-training surgeons. The “in-training surgeons” is the reference category.
