Table 4 Astrocytoma patients grouped by affectation (or not) of dentate nucleus at 3.25 years from surgery. Mean and SD standard scores (T and scaled scores: SS). Mann-Whitney U standard mean-scores statistically significant comparisons between: dentate-affected, dentate-unaffected patients versus control group, respectively. Dentate-affected compared with dentate-unaffected patients. Hemisphere dentate-affected compared with unaffected patients.
