Fig. 4From: Detection of gray matter microstructural changes in Alzheimer’s disease continuum using fiber orientationPartial correlation between radiality and image biomarkers. The red cluster shows a positive correlation with radiality, and the blue cluster shows a negative correlation. Cortical thickness showed positive correlations, and mean diffusivity, AV45, and AV1451 showed negative correlations. Color bar indicates p-value interval of 0.05 to 10− 10Back to article page
