Table 1 Main clinical and hemodynamic data of the overall population with the corresponding age-stratified comparisons between young (≤ 40 years old), middle-aged (41 to 60 years old), and older (> 60 years old) adults

From: Volume of the proximal half of the thoracic aorta is the most comprehensive FDG-PET/CT indicator of arterial aging throughout adulthood
