By contrast, however, in the ROC analyses for differentiating patients with sporadic miscarriage and RPL (Figure 2B), the corresponding AUCs for the aPT IgM, aPE IgG, aPE IgM, aEM IgG and combined aPE IgG and aEM IgG were 0.552, 0.508, 0.636, 0.600, and 0.575, respectively, indicating much lower efficiency in discriminating the above two groups. The gene discussed is CD40LG; the disease is Miscarriage.
