Categorical variables presented as percentages; continuous variables presented as mean±SD. P values comparing the distributions of age, sex, and race are not presented because these variables were used to match participants without AF to those with AF, ensuring balance in their distribution. AF indicates atrial fibrillation; eGFRcreat, creatinine‐based estimated glomerular filtration rate; FEV1, forced expiratory volume in 1 second; HDL‐c, high‐density lipoprotein cholesterol; LDL‐c, low‐density lipoprotein cholesterol.
