Multivariable models are adjusted for age at enrollment, sex, race (Caucasian, African American, or other), smoking history, RA disease duration, and baseline articular disease severity (DAS28).

Abbreviations: ILD = interstitial lung disease; OR = odds ratio; CI = confidence interval; ln = natural log; RA = rheumatoid arthritis; DAS28 = Disease Activity Score in 28 Joints.
