The Potential Diagnostic Biomarkers for the IgG Subclass in Coal Workers’ Pneumoconiosis

Figure 2

The ROC curve analysis of immunoglobulin test results between CWP and DEW. The ROC curve analysis was performed for (a) IgG1, (b) IgG2, (c) IgG3, (d) IgG4, (e) IgA, and (f) IgM to obtain the threshold values, sensitivity, and specificity. ROC: receiver operating characteristic. CWP: coal workers’ pneumoconiosis; DEWs: dust-exposed workers; HCs: healthy controls.
