For patients who had surgical resection, seizure outcome is classified according to the Engel classification9 (I, Seizure-free; II, rare disabling seizures (‘almost seizure-free’); III, worthwhile improvement; IV, no worthwhile improvement).
Awaiting, patients waiting for surgery; Refused, patients who refused surgery.
