Unadjusted and adjusted odds ratios (ORs) of singleton neonatal outcomes in the two groups

Outcomes	Unadjusted OR (95% CI)	P-value	Adjusted OR (95% CI)	P-value
PTB (< 37 weeks)	0.46 (0.22–0.95)	0.035	0.45 (0.22–0.96)	0.037
Macrosomia (> 4000 g)	0.83 (0.35–1.94)	0.666	0.91 (0.38–2.17)	0.827
LBW (< 2500 g)	0.77 (0.33–1.80)	0.548	0.77 (0.33–1.80)	0.542
LGA	0.63 (0.33–1.18)	0.142	0.64 (0.33–1.22)	0.174
SGA	2.67 (1.45–4.92)	0.002	2.50 (1.26–4.95)	0.009

ORs and 95% CI were based on the univariate analysis. Adjusted ORs and 95% CI were based on the multivariate logistic regression model after adjusting for age, BMI, number of FET cycles, infertility type, endometrial thickness, number of embryos transferred, embryo stage at transfer, number of high-quality embryos transferred
