The serum oestradiol/progesterone ratio on the day of OPU + 7, but not the day of OPU + 5, affects the rates of live birth in fresh blastocyst embryo transfer cycles

Table 3 Analysis of the correlation between the E₂/P ratio on OPU + 7 and pregnancy outcomes using multivariable regression analysis

Pregnancy Outcomes	Non-adjusted	Adjust
Positive hCG	1.01 (1.01, 1.02) < 0.0001	1.01 (1.01, 1.02) < 0.0001
Clinical pregnancy	1.01 (1.00, 1.01) < 0.0001	1.01 (1.00, 1.01) 0.0066
Ectopic pregnancy	0.95 (0.90, 1.00) 0.0552	0.97 (0.92, 1.02) 0.2601
Early pregnancy loss	0.99 (0.99, 1.00) 0.0697	0.99 (0.99, 1.00) 0.0559
Mid- and late-term pregnancy loss	0.99 (0.98, 1.01) 0.2607	0.99 (0.97, 1.00) 0.0684
Preterm birth	1.00 (1.00, 1.01) 0.0075	1.00 (1.00, 1.01) 0.0331
