  • 1-150 Using cholesterol as a continuous variable.

  • 1-151 Adjusted for age and sex.

  • 1-152 Adjusted for age, sex, diastolic blood pressure, height, smoking (cigarettes per day and a 0/1 term for ex-smokers) and pre-existing coronary heart disease (angina, severe chest pain lasting half an hour or more, or ischaemia on electrocardiogram).
