Figure 2. The annual risks of AF of different Taiwan AF scores and different risk categories based on the data of a 16‐year follow‐up.

After a 16‐year follow‐up, the risk of incident AF increased from 0.05%/year for patients with a score of −2 to 6.95%/year for those having scores ≥14. Patients were classified as low risk for scores −2 to 3, intermediate risk for scores 4 to 9, and high risk for scores ≥10. The annual risks of incident AF were 0.21%/year, 1.31%/year, and 3.37%/year for the low‐risk, intermediate‐risk, and high‐risk groups, respectively. AF indicates atrial fibrillation.
