Psoriatic arthritis and sacroiliitis are associated with increased vascular inflammation by 18-fluorodeoxyglucose positron emission tomography computed tomography: baseline report from the Psoriasis Atherosclerosis and Cardiometabolic Disease Initiative

Table 4 Sacroiliitis predicts vascular inflammation beyond psoriatic arthritis and CVD risk factors ^a

^aLikelihood ratio testing was applied in nested Tobit models to assess the incremental value of sacroiliitis in predicting aortic vascular inflammation. The outcome variable was aortic maximum standardized uptake (SUV_max). Independent variables in the different models were as follows: psoriatic arthritis (unadjusted); age, sex, BMI and psoriatic arthritis (partially adjusted); and age, sex, BMI, hypertension, dyslipidemia, diabetes, tobacco use and psoriatic arthritis (fully adjusted). χ² values are reported for each model. P-values < 0.05 were considered significant.
