CV = cardiovascular; AoCa = aortic calcification; Ag = Agatston score; HU = Hounsfield units; V/S = visceral-tosubcutaneous; IQR = interquartile ratio; Subsequent CV events defined as acute MI, CVA, CHF, or death
All comparisons of CT biomarkers with versus without events were statistically significant (p<0.001)
