  1. Overview on patient and mapping characteristics by gender, including age at exam, antiepileptics (AEDs: NA  no AED, L levetiracetam, SA other specified AEDs, NK AED status not known, UA unspecified AEDs), and presence of motor deficits (ND no deficit, D deficit). Furthermore, tumor location (RO Rolandic, FR frontal, PA parietal, PoG postcentral gyrus, TE temporal), tumor side (LH left hemisphere, RH right hemisphere), dominancy of the tumor hemisphere (NDO non-dominant, DO dominant), tumor-related edema (NE no edema, E edema), tumor entity (II astrocytoma WHO grade II, III astrocytoma WHO grade III, IV astrocytoma WHO grade IV, ME metastasis, X other entities), tumor recurrence (NR no recurrence, R recurrence), and tumor volume are displayed. In addition, resting motor threshold (rMT) values and year of mapping (Y10 exam year 2010, Y11 exam year 2011, Y12 exam year 2012, Y13 exam year 2013) are shown. All values are presented as number of patients, mean ± standard deviation (SD), or ranges. Dominancy data do not add up to 100 patients since it was not assessed in five patients
