The Potential Diagnostic Biomarkers for the IgG Subclass in Coal Workers’ Pneumoconiosis
Figure 3
Comparison of the IgG1/IgG3 ratio and IgG2/IgG3 ratio among the study groups. (a) IgG1/IgG3. (b) ROC analysis was performed for IgG1/IgG3 to determine the threshold value for differentiating between CWPs and DEWs. (c) IgG2/IgG3. (d) ROC analysis was performed for the E IgG2/IgG3 ratios to determine the threshold values for discriminating between CWPs and DEWs. . CWP: coal workers’ pneumoconiosis; DEWs: dust-exposed workers. ROC: receiver operating characteristic.
