INS and polycystic ovary syndrome: Finally, in the model that used CTRP13 as the dependent variable and BMI, FBG, log insulin, log HOMA-IR, log LH, log LH/FSH ratio, adiponectin and CTRP12 as independent variables, we observed that BMI demonstrated a significant association with CTRP13 in the non-PCOS (B = -0.371, p = 0.001) and with CTRP12 in PCOS (B = 0.218, p = 0.047) groups.
