EPILEPTIC SEIZURES
The primary efficacy outcome of this trial is the percentage decrease in the average seizure frequency per week during the postoperative 48-week compared to the preoperative period. Epileptic seizures must conform to the description of seizure characteristics in the ILAE, and the preoperative seizure frequency should be measured weekly and calculated based on valid seizure diaries only. The postoperative seizure frequency will be calculated in the same way, but should ensure that participants have valid seizure diaries for over 95% of the entire follow-up period.
