Unadjusted and adjusted odds ratios of reproductive outcomes of blastocysts transfer following L-FET versus HRT cycles.

	Unadjusted OR (95%CI )	Adjusted OR (95%CI )
Live birth rate	1.37(1.13-1.67)	1.30(1.06-1.58)
Abortion rate	0.60 (0.42-0.86)	0.63(0.44-0.90)
Preterm birth	0.98 (0.56-1.73)	0.99(0.56-1.77)
Low birthweight	0.98(0.51-1.89)	0.97(0.50-1.87)
Small for gestational age	0.84(0.54-1.30)	0.84(0.54-1.29)
Macrosomia	1.19(0.80-1.78)	1.18(0.79-1.78)
Large for gestational age	1.46(0.97-2.19)	1.45(0.97-2.17)

Analysis were adjusted for maternal age, body mass index, duration of infertility , type of infertility(Primary/ Secondary infertility), infertility diagnosis(Tubal/ Male/ Others) , basal antral follicle count, fertilization method(IVF/ICSI) and development stage of blastocysts(D5/D6) .CI, confidence interval.
