Impact of multidisciplinary steatotic liver disease management on bariatric surgery referral and clinical outcomes: A retrospective cohort study

Table 5 Outcomes in surgical vs non-surgical patients who were referred for bariatric surgery (mean ± SD, n/total n)

Patient characteristics		(+) Surgery	(-) Surgery	P value
Mean BMI (kg/m2)	RYGB	8.3 ± 5.4, 10/10	1.3 ± 3.9, 89/96	< 0.0001
	SG	9.1 ± 6.3, 21/21		< 0.0001
Mean weight reduction	RYGB	26.3 ± 10.3, 10/10	4.1 ± 10.2, 89/96	< 0.0001
	SG	27.7 ± 17.9, 21/21		< 0.0001
TBWL (%, mean ± SE, n/total n)	RYGB	20 ± 2.7, 10/10	2.5 ± 0.81, 89/96	< 0.0001
	SG	21 ± 2.1, 21/21		< 0.0001
∆NAFLD fibrosis score ± n/total n		-0.91 ± (22/31)	-0.008 ± (62/96)	0.005
∆FIB-4 score ± n/total n		-0.12 ± (30/31)	-0.055 ± (40/96)	0.58

Comparisons between groups analyzed using Welch’s unpaired t-test. BMI: Body mass index; RYGB: Roux-en-Y gastric bypass; SG: Sleeve gastrectomy; TBWL: Total body weight loss; NAFLD: Non-alcoholic fatty liver disease; FIB-4: Fibrosis-4.
