Fig. 2: Group differences in diffusion measures (FA, MD, RD, AD) and white matter volumes between OCD and HC.
From: Widespread alterations of white matter integrity in medication-free obsessive-compulsive disorder
A. FA reduction in OCD compared with HCs. The colour of each tract represents adjusted p values using false discovery rate. B. The colour blocks of each diffusion measures of pathways show the significance of group differences. FA fractional anisotropy, MD mean diffusivity, RD radial diffusivity, AD axial diffusivity, L left hemisphere, R right hemisphere, p_fdr p values adjusted using false discovery rate (FDR), ACOMM anterior commissure, MCP middle cerebellar peduncle, CC corpus callosum, ROSTRUM the rostrum of Corpus Callosum, GENU the genu of Corpus Callosum, BODYPF the prefrontal part of body of Corpus Callosum, BODYPM the premotor part of body of Corpus Callosum, BODYC the central part of body of Corpus Callosum, BODYT the temporal part of body of Corpus Callosum, BODYP the parietal part of body of Corpus Callosum, SPLENIUM the splenium of Corpus Callosum, AR acoustic radiation, ATR anterior thalamic radiation, CST corticospinal tract, OR optic radiation, AF arcuate fasciculus, CBD the dorsal part of the cingulum bundle, CBV the ventral part of the cingulum bundle, EMC extreme capsule, FAT frontal aslant tract, ILF inferior longitudinal fasciculus, MLF middle longitudinal fasciculus, SLF-I superior longitudinal fasciculus-I, SLF-II superior longitudinal fasciculus-II, SLF-III superior longitudinal fasciculus-III, UF uncinate fasciculus.
