Table 1 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
