Model 1 adjusted for age, sex, disease duration, and physician-reported disease activity and damage (SLEDAI and SDI)
Model 2 adjusted for age, sex, disease duration, obesity, smoking, and physician-reported disease activity and damage (SLEDAI and SDI). Further adjustment for income did not change results substantively
Model 3 adjusted for age, sex, disease duration, and patient-reported disease activity and damage (SLE activity [0 – 10 rating] and BILD)
