^aColumns represent each cognitive test. Rows represent two-sided bivariate correlations between cognitive test performance and sleep metric or PET uptake (see Materials and Methods). PiB DVR ROIs are comprised of weighted PiB DVR means within FreeSurfer regions as described by Villeneuve et al. (2015). FTP SUVR ROIs are comprised of weighted FTP SUVR means within FreeSurfer regions after PVC, as described by Maass et al. (2017).
