	Group A (DET with GQEʼs) n = 174	Group B (DET with MQE) n = 52	Group C (SET with GQE) n = 734	p*
Data presented as mean ± SD. DET: double embryo transfer; GQE: good quality embryo; MQE: mixed quality (one good quality plus one poor quality) embryos; SET: single embryo transfer. a There was a significant difference between DET with GQE and DET with MQE. b There was a significant difference between DET with GQE and SET with GQE. c There was a significant difference between DET with MQE and SET with GQE. d There was a significant difference between DET with GQE, DET with MQE and SET with GQE. * p-values with statistical significance (p < 0.05) are shown in bold.
