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 3 Sacroiliitis and psoriatic arthritis are positively related to vascular inflammation even after adjustment for CVD risk factors ^a

Regression factors	Age, sex and BMI	Age, sex, BMI, HTN, DL, DM, Tob
Sacroiliitis	0.268 (P < 0.001)	0.270 (P < 0.001)
Psoriatic arthritis	0.117 (P < 0.001)	0.124 (P < 0.001)

^aMultivariate linear regression analyses were performed using aortic maximum standardized uptake (SUV_max) as the dependent variable. Independent variables included in the model were (1) age, sex, body mass index (BMI) and either sacroiliitis (row 1, left column) or psoriatic arthritis (row 2, left column) or (2) age, sex, BMI, hypertension (HTN), dyslipidemia (DL), diabetes mellitus (DM), tobacco use (Tob) and either sacroiliitis (row 1, right column) or psoriatic arthritis (row 2, right column). β-coefficients (P-values) are reported for the effects of sacroiliitis or psoriatic arthritis on vascular inflammation (aortic SUV_max) after adjustment for cardiovascular disease risk factors (age, sex, BMI, HTN, DL, DM and Tob). P-values <0.05 were considered significant.
