Shown are baseline characteristics of 5,135 individuals free of atrial fibrillation and heart failure at baseline and with information on all conventional risk factors. For continuous traits, mean ± SD are given for normally distributed traits, and median (interquartile range) for right skewed traits. For categorical traits, n (%) are given.
