Table e-3. Neuroimaging results: Upper table reports grey matter (GM) areas commonly atrophied in all patient-groups vs. controls. T values of the same regions within each patient-group vs. controls contrast are also shown. Lower table reports GM areas differentially atrophied in each patient-group vs. controls and other patient-groups.
