Trophectoderm biopsy of blastocysts for a preimplantation genetic test does not affect serum β-hCG levels in early pregnancy: a study using propensity score matching

Table 2 Pregnancy outcomes of patients after PGT v. non-PGT following PS matching

	PGT	non-PGT	P
Total ongoing pregnancy ^a	79.7 (110)	79.4 (212)	0.942
Live birth^b	57.2 (79)	68.9 (184)
Ongoing pregnancy (following up)^c	18.8 (26)	9.0 (24)
Late miscarriage	3.6 (5)	1.5 (4)
Early miscarriage	12.3 (17)	16.5 (44)	0.267
Biochemical pregnancy loss	8.0 (11)	3.0 (8)	0.025
Ectopic pregnancy	0 (0)	1.1 (3)	0.554^d
Total	100.0 (138)	100.0 (267)

Note: ^aTotal ongoing pregnancy = live birth + ongoing pregnancy (following up) + late miscarriage.
^bLive birth only included patients transferred between January 2018 and March 2020.
^cOngoing pregnancy (following up) indicated gestations beyond 12 weeks, but the follow-up of live birth was not finished.
