The effect of trial design on sample size with an assumed trial drug efficacy of 80% reduction in seizure burden for 12h.

Outcome measures (OM) are total seizure burden (tSB) in minutes, post-intervention seizure burden (pSB) in minutes measured over a duration specified by the subscript in hours, seizure burden response (rSB) in minutes per hour, 1h pre-intervention vs. a post-intervention duration specified by the subscript in hours. Results are presented as sample size (95% CI).
