  1. The estimated intention-to-treat mean differences and 95% CIs were obtained after simple linear regression by using the bootstrap method with 1000 replications [39]
  2. The estimated per-protocol mean differences and 95% CIs were obtained after multiple linear regression adjusted for gender, age, education, cohabitation status, epilepsy duration, and seizures last year by using the bootstrap method with 1000 replications [39]
  3. SD Standard deviation, CI Confidence interval
