Multiple linear regression comparing resting energy expenditure in surgery and non-surgery controls

	Years after RYGB surgery
	Year 1	Year 2	Year 5
Intercept	29 (154)	− 17.6 (164)	−2(172)
Weight, kg	5.00 (1.69)^**	5.14 (1.71)^**	5.42 (1.79)^**
FFM, kg	− 4.41 (4.94)	−4.14(5.14)	− 6.02 (5.50)
SM, kg	17.37 (7.85)^*	15.11 (8.21)	17.70 (8.78)^*
Trunk organs, kg	201.3 (51.2)^***	226.2 (57.0)^***	211.1 (55.7)^***
Brain, kg	363.8 (119.7)^**	387.8 (125.0)^**	412.4 (127.1)^**
REE difference (RYGB minus CON), kcal/day	− 15.9 (54.8),p = 0.8 (1448 vs 1464)	− 46.9 (64.9), p = 0.47 (1415 vs 1462)	47.7 (83.0), p = 0.57 (1513 vs 1465)

Values are coefficients and standard errors (β (s.e.)) adjusted for weight, FFM, SM, organs, and brain. Group coded as RYGB 1, CON 0.
