Values are expressed as the or (%). DM-ILD-MDA5 Ab(+): DM patients with ILDs and anti-melanoma differentiation-associated protein 5 antibody-positive status; DM-nonILD-MSA16(-): DM patients without ILDs who were negative for 16 detectable myositis-specific antibodies; ILD: interstitial lung disease; DM: dermatomyositis.
