Rates of stroke recurrence (A) and mortality (B) are shown according to each potential cause compared with cardioembolic stroke (CE). Patients whose data regarding stroke recurrence or mortality at 3 months were missing were excluded from the analysis for the respective adverse events at 3 months. The number of patients in each group is shown below the graph. AE indicates arteriogenic emboli; CA, cancer associated; CPAF, covert paroxysmal atrial fibrillation; MCS, minor-risk potential cardioembolic sources; PE, paradoxical embolism; and UE, undetermined embolism.
