  1. Abbreviations: BMI, body mass index; CI, confidence interval; DZ, dizygotic.
  2. Note: means (95% CI) are observed across informative DZ sibpairs (N pairs=263) included in within-family association.
  3. Corrected for age, age2, birth, age × birth, age2 × birth as well as sex for men and women combined group only.
  4. bMen and women combined group also includes DZ opposite sex (DZOS) twin pairs.
