Please refer to supplementary Tables 1 and 2 for the summary of variables associated with aortic and splenic mean SUVmax (using a threshold p-value <0.05) that were carried forwards as covariates in multivariable analysis (Model 2 in each analysis). BMI = body mass index, CVD = cardiovascular disease, FRS = Framingham risk score, HDL = high density lipoprotein, HTN = hypertension, SE = standard error.
