To relate clinical outcomes to V-extra in patients with a previous COVID-19 infection (i.e., combined PCC- and UPC-group), voxel-based two-tailed linear regression models were employed, with V-extra as a dependent variable, covariates age and sex, and threshold-free cluster enhancement. Two-tailed P values were corrected for multiple comparisons across voxels using the family-wise error rate (FWE). Voxels with significantly different V-extra are indicated by hot shading and superimposed onto a T1w MRI template. Radiological orientation, i.e., left side of the image corresponds to the right side of the patient’s body; numbers denote the axial (z) position in millimeters. This statistic was based on n = 127 patients with previous COVID-19 infection.
