Imaginary numerical example of acute treatment effect in a population

Mean untreated attack duration (uD)	12 h
Successfully-treated attack duration (tD)	2 h
Change in mean time in ictal state (dTIS)	uD-tD = 12 − 2 = 10 h
Number of attacks treated (nA)	100
Probability of treatment success (SHR24) (pE)	50 %
Change in total time in ictal state (dtTIS)	dTIS*nA*pE = 10*100*50 % = 500 h
