Furthermore, binary logistic regression analysis between the groups indicated that AMH and quality of transferred blastocysts positively predicted the clinical pregnancy rate, with adjusted ORs of 1.01 (P=0.049) and 1.61 (P=0.006), respectively, while younger age had significantly positive effects on the miscarriage rate and live birth rate, with adjusted ORs of 0.91 and 1.10 (P=0.015 and 0.005), respectively. Here, AMH is linked to spontaneous abortion.
