Retrospective analysis of the endometrial preparation protocols for frozen-thawed embryo transfer cycles in women with endometriosis

Table 4 Adjusted odds ratios of pregnancy outcomes in endometriosis patients with GnRHa-HRT endometrial preparation protocol

Variable	Two injections of GnRHa vs. One injection of GnRHa	Three injections of GnRHa vs. One injection of GnRHa	Two injections of GnRHa vs. Three injection of GnRHa
Variable	Adjusted OR (95% CI)	Adjusted OR (95% CI)	Adjusted OR (95% CI)
Clinical Pregnancy^a	0.867(0.533–1.412)	0.887(0.431–1.828)	0.977(0.444–2.154)
Live Birth^b	0.641(0.391–1.052)	0.642(0.305–1.35)	0.999(0.442–2.261)
Early Miscarriage^c	3.116(1.079–8.998)^d	2.472(0.644–9.488)	1.26(0.298–5.34)

Note: Adjusted odds ratios (AORs) and 95% CIs are based on the multiple logistic regression model. No statistical difference for all results
