Mean and absolute deviation (AD) over the performance parameters obtained using the ten reference windows randomly selected for each patient. Results are rounded and expressed as mean ± AD. SOPmax: maximum seizure occurrence period; SEN: sensitivity; SPE: specificity; FPR: false prediction rate; PT: portion of time under false predictions; MPT: Mean prediction time.
