IIM, idiopathic inflammatory myopathy; ILD, interstitial lung disease; MAAs, myositis-associated autoantibodies; CADM, clinically amyopathic dermatomyositis; DM, dermatomyositis; PM, polymyositis; OM, overlap myositis; ENA, extractable nuclear antigen; NSIP, nonspecific interstitial pneumonia; OP, organizing pneumonia. "+": weakly positive signal intensity ranged from 11 to 25 U for anti-SAE1 antibody via line immunoblot assay method. "++": strongly positive signal intensity ranged from 26 to 50 U for anti-SAE1 antibody via line immunoblot assay method."+++": strongly positive signal intensity above 50 U for anti-SAE1 antibody via line immunoblot assay method.
