  1. Studies are sorted according to the statistical method used for obtaining the prognostic factors. RBANS Repeatable Battery for the Assessment of Neuropsychological Status; ↑ the higher the prognostic factor, the higher the improvement/positive correlation; ↓ the lower the prognostic factor, the higher the improvement/negative correlation; → no direction of effect reported; * significant; x unclear reporting
