Two-year post-surgical outcomes were based on the ILAE classification system (class 1–6).
F = female; FCD = focal cortical dysplasia; HS/MTS = hippocampal sclerosis/mesial temporal sclerosis; HUP = Hospital of the University of Pennsylvania; LFL = left frontal lobe; LFPL = left frontoparietal lobe; LTL = left temporal lobe; M = male; MCD = malformation of cortical development; mo = months; NR = no resection; RFL = right frontal lobe; RFTL = right frontotemporal lobe; RTL = right temporal lobe.
