Mean and standard deviations of direct (DS) and standard scores (T, SS: scaled scores and Z). Mann-Whitney U means-standard scores comparisons for the statistically significant applied tests between medulloblastoma group (at 6.47 years from surgery + with treatments) and astrocytoma group (at 3.25 years from surgery, without treatments) with the control group, respectively.
