IFIH1 and interstitial lung disease: Another large-scale single-center cohort study in China proposed a model called the “FLAIR score,” which combines ferritin(<636 ng/mL, 0; ≥636 ng/mL, 2), LDH(<355 U/L, 0; ≥355 U/L, 2), anti-MDA5 antibody(negative, 0; +, 2; ++, 3; +++, 4), HRCT imaging scores(<133, 0; ≥133, 3), and RPILD(non-RPILD, 0; RPILD, 2) to predict the mortality of amyopathic dermatomyositis (ADM)-associated ILD (25).
