Each person was classified as controlled or uncontrolled, depending on whether they brought their seizures under complete control during the treatment or remained uncontrolled (any seizure activity led to a classification of 'uncontrolled' for the purposes of this study, and there was no distinction made for degree of improvement). In addition information on four other variables was collected, so that the following five variables were available for analysis in this study:
(1) SEIZCON: classification as controlled or uncontrolled at the end of treatment;
(2) ONSETAGE: age when seizures first began;
(3) YRSUNCON: number of years that seizures had been uncontrolled at the time treatment began;
(4) FREQSEIZ: frequency of seizures (number per month) at the time treatment began;
(5) NUMSESS: the number of treatment sessions until treatment was stopped.
