CP: cerebral palsy; EF: executive function; IQ: intelligence quotient; IQR: interquartile range; NS: no significant; SD: standard deviation. Reasons for missing data: aAnarthria accompanied by very severe motor impairments that preclude to use an appropriate response system for the test used; bAnarthria or severe dysarthria.
⁎Bonferroni correction for multiple-comparison was applied and significance is at level set of 0.006.
†Data in one or both groups is not normally distributed, thus, non-parametric test is applied and median (IQR) is indicated in italic.
+Higher scores indicate worse performance.
