Patients were grouped by surgical outcome. Second column shows patients who had a favourable surgical outcome. Third column shows patients who had a poor surgical outcome. FCD = focal cortical dysplasia; HS = hippocampal sclerosis; LFL = left frontal lobe; LFPL = left frontoparietal lobe; LPL = left parietal lobe; LTL = left temporal lobe; MTS = mesial temporal sclerosis; PNH = periventricular nodular heterotopia; RF = right frontal; RFL = right frontal lobe; RFPL = right frontoparietal lobe; RPL = right parietal lobe; RTL = right temporal lobe; SD = standard deviation; TSC = tuberous sclerosis complex.

^aData for these fields were unknown in a minority of patients and thus were not included in the table.
