Health related quality of life after gastric bypass or intensive lifestyle intervention: a controlled clinical study

Table 2 One way between-groups analysis of variance on five dimensions of HRQL in morbidly obese patients undergoing either RYGB or ILI

	Changes from baseline		Adjusted between group difference, mean (95% CI)	P	ES
	RYGB	ILI
	(n=76)	(n=63)
Physical dimension^a	16.8 (9.7)	4.9 (9.4)	8.6 (4.6,12.6)	<.001	.83
Mental dimension^a	9.6 (9.1)	3.5 (8.9)	5.4 (1.5,9.3)	.007	.50
Emotional dimension^b	42.7 (25.5)	15.7 (21.7)	25.2 (15.0,35.4)	<.001	1.06
Number of obesity symptoms^c	−5.3 (4.6)	−2.9 (4.7)	−2.3 (−4.5,-.6)	.012	.56
Symptom distress^d	−25.2 (20.7)	−14.3 (16.5)	−8.7 (−15.4,-1.8)	.013	.37

Adjustments were made for age at the onset of obesity and baseline values of age, BMI physical activity level, and HRQL. (a) SF-36 (scale 0–100). (b) OWLQOL (scale 0–102). (c) WRSM (scale 0–20). (d) WRSM (scale 0–120). Statistical significance (P) and effect size (ES) are reported.
