Figure 5. — Correlation of serum β-HCG with P, FSH, ET, PSV, and RI levels. (A) Logistic regression analysis evinced that serum β-HCG and ET harbored positive association, R = 0.573, P < .05. (B) Serum β-HCG held positive link with PSV, R = 0.682, P < .05. (C) Serum β-HCG possessed negative relation with RI, r = −0.637, P < .05. (D) Serum β-HCG owned positive relationship with serum P, R = 0.594, P < .05. (E) Serum β-HCG had positive correlation with serum FSH, R = 0.615, P < .05. ET = endometrial thickness, FSH = follicle stimulating estrogen,P = progesterone, PSV = peak systolic velocity, RI = resistance index, β-HCG = β-human chorionic gonadotropin.
