Mann–Whitney tests were performed to determine statistical significance between subgroups. Additionally, Benjamini–Hochberg correction for multiple comparisons with an FDR of 0.1 was performed, with p-values that remained significant after correction indicated in bold font. R, right; L, left; WM, white matter.
