Refining Clinical Risk Stratification for Predicting Stroke and Thromboembolism in Atrial Fibrillation Using a Novel Risk Factor-Based Approach
Key result
The novel risk factor-based stroke risk stratification schema improved predictive value for thromboembolism compared to the CHADS(2) schema in atrial fibrillation patients.

Implication
May support refined AF risk stratification; hypothesis-generating and should not yet change practice.
