Joint Assessment of Structural, Perfusion, and Diffusion MRI in Alzheimer's Disease and Frontotemporal Dementia
Figure 3
Conditional load of one modality relative to another as a function of the level of abnormality (T-score) for AD (a) and FTD (b). Note, vertical axes in (a) and (b) are plotted on a logarithmic scale (base-10) where a value larger than one indicates the load from a particular modality was higher than the load from reference modality. Conditional load lower than 1 indicated opposite relations between modalities. The extent to which differences in the conditional loads among modalities are above chance () across the level of abnormality is indicated in plot (c) for AD and in plot (d) for FTD. Note, values in (c) and (d) are also plotted on a logarithmic scale. The horizontal dash lines indicate significance.
