Hazard ratios for mortality according to cancer groups

	Deaths		Hazard ratios for cancer deaths^a
	Surgery group N = 6,596	Control group N = 9,442	Surgery vs. control groups
Cancer site	N (rates/1,000 person years)	N (rates/1,000 person years)	Hazard ratio (95% CI)	P value^*
All cancers: males and females combined	41 (0.50)	107 (0.94)	0.54 (0.37–0.78)	0.001
All cancers: males only	10 (0.12)	24 (0.21)	0.70 (0.34–1.48)	0.35
All cancers: females only	31 (0.38)	83 (0.73)	0.38 (0.23–0.64)	0.0003
Obesity-related cancers^b	20 (0.24)	55 (0.48)	0.54 (0.32–0.90)	0.02
Nonobesity-related cancers^c	21 (0.25)	52 (0.46)	0.53 (0.31–0.91)	0.02

CI, 95% confidence interval.

Hazard ratios adjusted for age, sex and BMI. Prevalent cancers at baseline were excluded.

Obesity-related cancers included esophageal adenocarcinomas, colorectal, pancreas, postmenopausal breast, corpus and uterus, kidney, non-Hodgkin lymphoma, leukemia, multiple myeloma, liver, and gallbaldder.

All cancers that are not included as obesity-related cancers.

P values are unadjusted for multiple comparisons.
