IFIH1 and interstitial lung disease: In our univariate analysis, anti-MDA5 antibodies (HR=3.46; 95% CI=1.34-8.96) and ILD (HR=1.83; 95% CI=1.03-3.27) were significant predictors, but multivariate analysis did not show significance for anti-MDA5 antibodies (HR=1.90; 95% CI=0.64-5.60) and ILD (HR=0.92; 95% CI=0.37-2.29).
