Figure 2. Cumulative proportion of activation-related epileptiform abnormalities by seizure type.

Figure 2

A. Epileptiform abnormalities due to sleep activation among all subjects with incident epilepsy who slept, by seizure type (1 year or more).

B. Epileptiform abnormalities due to hyperventilation among all subjects with incident epilepsy who had a hyperventilation procedure, by seizure type (1 year or more).

C. Epileptiform abnormalities due to photic stimulation among all subjects with incident epilepsy who had a photic stimulation procedure, by seizure type (1 year or more).

The Ns for each EEG represent the effective sample size, which consider the censored data and the probability at midpoint in actuarial lifetable.
