Distribution of idiopathic inflammatory myopathy (IIM) duration at cancer diagnosis by autoantibody status. There were tight temporal relationships between the onset of myositis and cancer diagnosis in patients with antibodies to TIF1-γ, NXP2, and SAE1. The groups of patients with anti-HMGCR, anti-Jo-1 antibodies, anti-PL-12 antibodies, and MSAs-negative patients had similar close temporal relationships between the onset of myositis and cancer diagnosis. Horizontal bars indicate median duration). PM, polymyositis; DM, dermatomyositis
