Crude and Adjusted Associations of PAD3/4 Cross-Reactive Antibodies with Pulmonary Outcomes in RA.

*Adjusted for age, RA duration, RF, CCP2, IL-6, SHS. **Adjusted for age, gender, RF, CCP2, RA duration, DAS28, prednisone use, biologic DMARD use, current and past smoking, and SHS. †β coefficients are Odds Ratios. ILD = interstitial lung disease; GGO = ground glass opacification; R/TB/HC = reticulation/traction bronchiectasis/honeycombing; PFT = pulmonary function testing; Impaired Diff = impaired diffusion; RA = rheumatoid arthritis; RF = rheumatoid factor; CCP2 = 2nd generation anti-cyclic citrullinated peptide antibody; DAS = disease activity score; CRP = C-reactive protein; IL = interleukin; SHS = Total modified Sharp-van der Heijde Score; DMARD = disease modifying anti-rheumatic drug.
