MPO, NE, and IL-6 in respiratory infections of IIM patients. In the ASS and DM patients with respiratory infections compared to patients without respiratory infections, MPO (a) (), NE (c) (), and IL-6 (e) () were significantly higher. ROC analysis showed that the AUC values of MPO (b) at 0.692 (95% CI 0.523–0.861, ), NE (d) at 0.692 (95% CI 0.5251–0.859, ), and AUC values of IL-6 (f) at 0.720 (95% CI 0.561–0.880, ). (g) AAT was not significantly different in the two groups of patients.
