Associations of CT Muscle Area and Density With Functional Outcomes and Mortality Across Anatomical Regions in Older Men.

Background: The automated segmentation of computed tomography (CT) images has made their opportunistic use more feasible, yet, the association of muscle area and density from multiple anatomical regions with functional outcomes and mortality risk in older adults has not been fully explored. We aimed...
