Analysis of the relationship between PDIA3Ab total serum IgG expression and the occurrence of PCOS among euthyroid AIT women. (a) A logistic plot showing the probability of concurrent polycystic ovary syndrome relative to PDIA3Ab total serum IgG expression. (b) The ROC curve of PDIA3Ab total serum IgG expression for prediction of PCOS. The area under the curve was 0.700 ± 0.053 (P = 0.001). (c) The titer-dependent relationship between PDIA3Ab total serum IgG expression and the prevalence of PCOS. Four grades were divided based on the quartile of OD value ratio of PDIA3Ab total serum IgG in the whole euthyroid AIT women
