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 |

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.
