Note. Model adjusted for age and sex. WMH = white matter hyperintensities; BTV = brain tissue volume; ICV = intracranial volume; PVS = basal ganglia perivascular spaces; SVD = small vessel disease; CRAE = central retinal artery equivalent; CRVE = central vein retinal equivalent; BSTDa = standard deviation of arteriolar widths in Zone B; BSTDv = standard deviation of venular widths in Zone B; FDa = fractal dimension arteriolar; FDv = fractal dimension venular; TORTa = arteriolar tortuosity; TORTv = venular tortuosity; BCa = arteriolar branching coefficient; BCv = venular branching coefficient; AFa = arteriolar asymmetry factor; AFv = venular asymmetry factor; LDRa = arteriolar length diameter ratio; LRDv = venular length diameter ratio; Gradient a = arteriolar width gradient; Gradient v = venular width gradient; PC = principal component; Bolded values are statistically significant. WML % volumes and tortuosity log transformed. β, Standardised regression coefficients.
*p < 0.05; **p < 0.01; ***p < 0.001; all p-values corrected for False Discovery Rate. aValue was statistically significant at p < 0.05 before FDR correction.
