†

Cox model with all three ECG variables entered, adjusted for age, BMI, diastolic and systolic blood pressures, fasting glucose, GHb, HDL and LDL cholesterol levels, triglyceride level, albuminuria, alcohol use, history of smoking, and study center. Prevalent CHD was included as a covariate only in the total population. HR, hazard ratio.
