DAS28: disease activity score; HAQ-Di: Health Assessment Questionnaire-Disability Index; ESR: erythrocyte sedimentation rate; MTX: methotrexate; anti-CCP2 titers: anti-cyclic citrullinated peptide antibodies titers (second generation); OR: odds ratios; 95% CI: 95% confidence interval. Variables were adjusted using logistic regression analysis. Dependent variable: presence or absence of interstitial lung disease. Covariates: age (quantitative), disease duration >5 years (qualitative), smoke exposure (qualitative), DAS28 (quantitative), HAQ-Di (quantitative), anti-CCP2 titers (quantitative), +rheumatoid factor (qualitative), and MTX duration in treatment (quantitative). |
