  1. Group means adjusted for age and results of ANCOVAs and post-hoc pairwise comparisons are shown. Results are bolded if significant (p < 0.05 for ANCOVAs or p < 0.0167 for post-hoc tests (Bonferroni Correction)).
  2. TD typically developing, AIS arterial ischemic stroke, PVI periventricular venous infarct.
