Pre- and postoperative seizures in operated patients. Schematic presentation of pre- and postoperative seizures in patients with a single supratentorial brain metastasis. Bold arrows indicate patients who had no diagnosis of BTRE and remained seizure free after surgery (upper bold arrow) or had a diagnosis of BTRE and ongoing seizures following surgery (lower bold arrow). Thin arrows indicate patients who were so far seizure free and developed postoperative BTRE (upper, down-going thin arrow) or patients with BTRE who became seizure free after surgery (lower up-going thin arrow). P-value as indicated (McNemar’s test).
