Forest plot of univariate A and multivariate B Cox regression analyses for the risk factors for all-cause mortality in 69 patients in the ADM-NSIP/OP groups. p < 0.05 was considered significant. *Due to insufficient data, ferritin, DLco and oxygenation indices were not included in the multivariate Cox regression model. ** Anti-MDA5 antibody, although not significant in univariate Cox analysis, is widely recognized as an important prognostic marker in myositis-associated ILD and, therefore, was included in the multivariate model
