Survival analysis of dermatomyositis (DM) patients related to serum neopterin levels. (a) Receiver operating characteristics (ROC) for the prediction of fatal outcome in DM patients showed that a cut‐off value of 22·1 nmol/l could distinguish non‐survivors from survivors with an area under the curve (AUC) of 0·777 [95% confidence interval (CI) = 0·697–0·857, P < 0·001]. (b) Survival curves of DM patients subgrouped by serum neopterin levels at a cut‐off value of 22·1 nmol/l. (c) Survival curves of DM patients subgrouped by serum neopterin into three groups: those with baseline serum neopterin < 22·1, those with baseline serum neopterin 22·1–44·2 and those with baseline serum neopterin > 44·2.
