Results of multivariable linear regression analyses for postoperative length of stay (LOS)

Primary outcome	Pre-intervention group (n = 93)			Post-intervention group (n = 99)			Exp(β-Coeff)^a	p-value^b
Primary outcome	Mean	SD^*	Exp(SE^○)^a	Mean	SD^*	Exp(SE^○)^a	Exp(β-Coeff)^a	p-value^b
Length of postoperative hospital stay (in hours) without adjustment for confounders	84.28	10.35	1.07	115.92	10.98	1.10	1.38	< 0.01
Length of postoperative hospital stay (in hours) with adjustment for confounders^c	74.13	10.31	1.07	94.29	10.89	1.09	1.27	< 0.01

^*SD = Standard Deviation, ^○SE = Standard Error

^aThe dependent variable was log-transformed to meet the assumptions of the linear regression

^bA p-value < 0.05 was considered statistically significant

^cCorrected for the variable: psychiatry or chronic pain and complications
