Table 3.

Relationships between embryos and rates of biochemical pregnancy loss

Embryo %(n)	PGT	non-PGT	P_{PGT vs non-PGT}
fair	6.7 (1)	4.0 (1)	1.000^a
good	8.1 (10)	2.9 (7)	0.025
P_{fair vs good}	1.000^a	0.550^a
Days of embryo
5	6.1 (6)	2.7 (5)	0.197^a
6	12.8 (5)	3.8 (3)	0.113^a
P_{day 5 vs day 6}	0.292^a	0.698 ^a

Note: ^aFisher Exact Test was used. P_{fair vs good} indicated a comparison between fair embryos and good embryos

P_{day 5 vs day 6} indicated a comparison between day 5 embryos and day 6 embryos. P_{PGT vs non-PGT} indicated a comparison between PGT cycles and non-PGT cycles
