Comparison of pairwise group differences in cerebellar volumes across methods for accounting for aTBV. Heat maps show p values for significant volume differences between karyotype groups for multiple measures of cerebellar volume. Each heat map refers to a different method of controlling for brain size effects. p values are shown on a −log10 scale, with more intense colors representing smaller p values. Gray cells denote pairwise contrasts that are not statistically significant (Bonferroni-corrected, p > 0.05). All significant contrasts involve volume reductions.
