Cumulative risks of atrial fibrillation and stroke stratified by days meeting guideline-recommended moderate-to-vigorous physical activity levels. Depicted is the cumulative risk of atrial fibrillation (upper panels) and stroke (lower panels) stratified by the number of days individuals met the average daily moderate-to-vigorous physical activity levels corresponding to the European Society of Cardiology,¹⁴ American Heart Association,¹³ and World Health Organization standard thresholds (≥25 min/day, left panels),¹² and the World Health Organization threshold for additional health benefits (≥45 min/day, right panels).¹² Only individuals contributing a full week of accelerometer data are included (n = 88 644 for atrial fibrillation analyses; n = 87 536 for stroke analyses).
