Weight loss at 12 mo after laparoscopic re-sleeve gastrectomy

	Value (n = 11) before LRSG mean ± SD	After LRSG mean ± SD	Mean change (SD)	95%CI	P value
Absolute weight (kg)	100.3 ± 17.5	82.9 ± 14.7	-17.4 (± 7.8)	-12.0--22.6	< 0.001
BMI (kg/m2)	38.9 ± 3.8	32.2 ± 3.9	-6.6 (± 2.7)	-4.8--8.5	< 0.001
Excess weight (kg)	43.2 ± 10.1	25.8 ± 9.5	-17.4 (± 7.8)	-12.0--22.6	< 0.001
Excess weight (%)	75.4 ± 11.6	45.4 ± 16.5	-29.2 (± 12.4)	-20.8--37.6	< 0.001
Excess weight loss (%)	25.3 ± 14.2	56.8 ± 12.4	+31.0 (± 15.8)	41.6-20.4	< 0.001

P value is calculated with paired t test assessing change from LRSG. BMI: Body mass index; LRSG: Laparoscopic re-sleeve gastrectomy.
