Figure 1 (A) All cycles (n = 2,055): live birth rates are significantly lower in group 3 as compared with group 1 (P=.012) and group 2 (P=.007). (B) Gonadotropin-releasing hormone agonist cycles (n = 2,062): live birth rates are significantly lower in group 3 as compared with group 1 (P=.034) and group 2 (P=.01). (C) Gonadotropin-releasing hormone antagonist cycles (n = 493): There are no significant differences between the P groups.
