Reproductive outcomes of patients after the first single embryo transfer following ER Map test. Positive B-hCG rates (green bars) and clinical pregnancy rates (grey bars) comparison between the group of patients that followed ER Map progesterone pretreatment and those that deviated more than 12h from this recommendation. X2 test, *p = 0.02, #p < 0.001 n = 746 sET (ER Map WOI N = 681, > 12h deviation n = 65).
