This table listed the tracts with at least one Spearman's correlation coefficient at a FDR-corrected p < 0.05.
p < 0.01.
A FDR-corrected p < 0.05.
Associations with both subjective and objective cognition.
SCD, subjective cognitive decline; R, right; L, left; ICP, inferior cerebellar peduncle; CST pyramids, pyramids segment of corticospinal tract; PCR, posterior corona radiata; SCR, superior corona radiata; MoCA, Montreal cognitive assessment; IPAQ-SF MET, international physical activity questionnaire-short form, metabolic equivalent task minute per week; IV, intradaily variability; IS, interdaily stability; FA, fractional anisotropy; MD, mean diffusivity; FDR, false discovery rate.
