Flow diagram of study participants for END models. A total of 163 patients were eligible to enter this study. First, all patients were evaluated for END model A and 9 patients were stratified. The others were selected for evaluation of END model B when a single subcortical infarction of less than 20mm in diameter in the territory of penetrating arteries in DWI was present. After the exclusion of patients with positive model END A (N=9) and small subcortical infarction (N=65), the remaining patients (N=89) were evaluated for END model C. After excluding patients who were positive for END model C (N=22), the others with negative END model C (N=67) were surveyed for END model D.
