Rate ratios (RRs) and 95% CIs of coffee consumption stratified by BMI in relation to endometrial cancer for women in the Swedish Mammography Cohort.
Coffee consumption at baseline | No of cases | ≤1 cups | 2–3 cups | ≥4 cups | Ptrend | Per 1 cup† | |
---|---|---|---|---|---|---|---|
RR (95% CI)* | Normal weight (BMI 20–25) | 246 | 1.00 (ref) | 1.21 (0.84–1.73) | 1.13 (0.72–1.78) | 0.79 | 1.00 (0.88–1.15) |
Overweight (BMI 26–30) | 219 | 1.00 (ref) | 0.65 (0.46–0.92) | 0.72 (0.46–1.14) | 0.07 | 0.88 (0.77–1.00) | |
