  1. ± compared with patients without the condition/medication at baseline.
  2. § Compared with patients in the white/not recorded group
  3. Models also included fractional polynomial terms for age, body mass index and systolic blood pressure. The fractional polynomial terms were as follows:
  4. Both sexes: age terms were (age/10)3 and (age/10)3*ln(age/10)
  5. Both sexes: bmi terms were (bmi/10)-2 and (bmi/10)-2*ln(bmi/10)
  6. Women: sbp terms were (sbp/100)-2 and (sbp/100)-2*ln(sbp/100)
  7. Men: sbp terms were (sbp/100)-2 and (sbp/100)-0.5
  8. The model also included interactions between the age terms and type 1 diabetes, type 2 diabetes and treated hypertension
