*Follow up was censored at 10 years in the men's cohorts of the British Regional Heart Study (BRHS), the Caerphilly Study and the Speedwell Study.

†The median follow up was 4.7 years (range 3.4–5.7 years) for women in the British Women's Heart and Health Study (BWHHS) and the age group was older than in the men's cohorts.

‡Coronary heart disease (CHD) and cardiovascular disease (CVD) excluded those with a prior diagnosis of myocardial infarction, stroke and diabetes from the analysis.

HDL, high density lipoprotein; HR, hazard ratio; SBP, systolic blood pressure; TC, total cholesterol.
