† Model 1 (n = 51) adjusted for age, race, family history of breast cancer, parity and menarche < 12 years. Multiple R2 = 0.56 ††P-trend from linear regression models where trend is measured as a continuous value after assigning the normal weight category 0, overweight category 1, and obese category 2. P-values for these models where BMI is measured as a non-categorized continuous variable are available in Table 3. |
