Figure 1. Patient Selection Flowchart.
Incomplete data for most patients meant that the preimplantation, implantation, or postimplantation neuroimaging did not fit the inclusion criteria (slices of <2 mm). The rate of good surgical outcome (Engel class I) was 42.7% in patients included in the study and 41.9% in patients excluded (P = .91). CHUGA indicates Grenoble-Alpes University Hospital; MNI, Montreal Neurological Institute; and SEEG, stereoelectroencephalography.
