Comparisons of hemispheric asymmetries of global graph theoretical metrics between the tea-drinking group (denoted by T) and the non-tea drinking group (denoted by NT). A positive value in the hemispheric asymmetry indicates the leftward hemispheric asymmetry while a negative value indicates the rightward hemispheric asymmetry. Asterisks represent significance level obtained by permutation test (* corrected p< 0.05). (A) Hemispheric asymmetries of global graph theoretical metrics for functional connectivity network. (B) Hemispheric asymmetries of global graph theoretical metrics for structural connectivity network.
