Thoracic aorta calcium estimated by computed tomography (CT): calcification volume quantified by extracting the aorta calcium with density and without diabetesiplied by 100 to express the results as a percentage.matic software; thoracic aorta was divided into 4 sites, aortic root calcium (ARC), ascending aorta calcium (ATAC), AAC(aortic arch calcium), DTAC(descending thoracic aorta calcium) and TC (total calcium) were all calculated

AAC by routine chest radiography: the circumferences of aortic arch was divided into 16 sites, the number of sectors with calcification was calculated and multiplied by 100 to express the results as a percentage
