The odds ratio of PDIA3Ab total serum IgG expression related to PCOS in the euthyroid women with AIT (n = 98, Fig. 2a) and those without AIT (n = 185, Fig. 2b). Adjusted OR were shown according to quartile of OD value ratio of PDIA3Ab total serum IgG (Fig. 2a: Q1, < 0.5273; Q2, 0.5273 to 0.6977; Q3, 0.6977 to 0.9415; Q4, > 0.9415. Figure 2b: Q1, < 0.344; Q2, 0.344 to 0.4369; Q3, 0.4369 to 0.5494; Q4, > 0.5494). Q1 was the reference group in all models. Binary logistic regression analysis was performed in models 1–3 after adjusting potential confounding factors. Model (1) Adjusted for age. Model (2) Adjusted for age and BMI. Model (3) Adjusted for age, BMI, serum levels of FT4, FT3, TSH, TPOAb (only in euthyroid AIT women), and TgAb (only in euthyroid AIT women)
