Receiver operator characteristic (ROC) curve for anti-NT5c1A antibodies with sIBM (n = 43) as the true state against (A) all control sera (n = 615), (B) healthy controls (n = 78), (C) idiopathic inflammatory myopathies (n = 142), and (D) systemic lupus erythematosus (n = 199). AUC, area under the curve; CI, confidence interval; FPF, false positive fraction; HC, healthy controls; IIM, idiopathic inflammatory myopathies; SLE, systemic lupus erythematosus; TPF, true positive fraction.
