Active Rash, Interstitial Lung Disease, and Neutrophil to Lymphocyte Ratio and Mortality in Dermatomyositis

In this study, active rash, ILD, and elevated NLR were independently associated with in-hospital mortality in patients with DM, regardless of disease subtype or myositis-specific autoantibody status. Recognizing these high-risk features may guide inpatient management and support future risk stratification strategies.
