*Also adjusted for triglycerides, platelets, white cell count, red blood cell count, haemoglobin, packed cell volume, alcohol use, social class, factor V and factor VIII.
†Unadjusted OR=3.31; age-adjusted OR=3.34. CHD deaths within 10 years (n=61): adjusted OR=2.18 (95% CI 0.38 to 12.62). CHD deaths after 10 years (n=201): adjusted OR=4.95 (95% CI 1.26 to 19.48), interaction p=0.47. Adjusted for age at death: OR=3.97.
