In addition, the progesterone level during ovulation induction was not the main outcome measure in those studies, and the power of test is insufficient. In the PSM 1 cohort, patients in the LE GnRH-a group presented higher progesterone levels (1.22 0.95 ng/mL vs 0.86 0.60 ng/mL, P < 0.001), with a higher proportion of patients with progesterone level > 1.5 ng/mL (24.81% vs 7.52%, P < 0.001). The matching ratio was 1:1, and the matching range of the score was 0.01.
