a,bResults correspond to Cox proportional hazards model adjusted for age, sex, race, center, education, smoking, BMI, hypertension, total cholesterol, HDL cholesterol, diabetes, prevalent and time-dependent CHD, prevalent and time-dependent HF (for the AF analysis only), prevalent and time-dependent stroke, time-dependent AF (for the HF analysis only). Model a additionally adjusted for time-dependent pacemaker implantation.
