Correction: First external validation of sensitivity and specificity of the European League Against Rheumatism (EULAR)/American College of Rheumatology (ACR) classification criteria for idiopathic inflammatory myopathies with a Japanese cohort

Abstract

In the main text “The new criteria were therefore validated with a Japanese cohort. Receiver operating characteristics (ROC) curve analysis indicated that the area under the curve (AUC) for all Japanese cases, the cases with muscle biopsy data, and the cases without muscle biopsy data was 0.97, 0.87, and 0.97, respectively (online supplementary Figure S2)”. AUC=0.9562 in the graph of Fig 2S (a) was mistakenly referred as 0.97.
