Receiver operating characteristic curves for the seizure recurrence risk score models. a Validation in the early onset post-ischemic stroke seizure (PSSi) group, and b validation in the late onset PSSi group. Score 1-1 included all 10 items, whereas score 2-1 excluded age, sex, and atrial fibrillation factors. Score 3-1 (male sex, atrial fibrillation, cortical involvement, functional disability, and partial seizure) in early onset and score 4 (younger age at seizure onset, male sex, large stroke lesion, and partial seizure) in late onset patients (solid line) were composed of more prevalent items (p < 0.3) in each recurrent group that showed the largest area under the curve (AUC) among each group’s suggested scores. Predictive scores from MRC Multicenter trial for Early Epilepsy and Single Seizures (MESS) and Post-Stroke Epilepsy Risk Scale (PoSERS) study were applied to compare our patients. However, they demonstrated little efficacy for detecting or discriminating seizure recurrence in patients with early and late onset PSSi
