  1. Abbreviations: BMI, body mass index; DBP, diastolic blood pressure; DOS, dizygotic opposite sex; DZM, dizygotic male; DZF, dizygotic female; MZF, monozygotic female; MZM, monozygotic male; SBP, systolic blood pressure.
  2. aTwin correlations for SBP and DBP are shown before and after adjustment for BMI. All measures were log-transformed and adjusted for age, sex and study site.
