Table 1:

Adjusted odds ratios in singleton live birth deliveries for preterm delivery, low birthweight and small for gestational age in subfertile and ART groups compared to fertile as reported by Declercq et al (25)

	Subfertile	ART
Category	AOR (95% CI)	AOR (95% CI)³
	Reference Fertile	Reference Fertile	Reference Subfertile

Preterm (<37 weeks)	1.24 (1.12–1.38)	1.53 (1.40–1.67)	1.23 (1.08–1.41)

Low Birthweight (<2,500gms)	1.20 (1.06–1.36)	1.51 (1.37–1.67)	1.26 (1.08–1.47)

Small for Gestational Age	0.95 (0.85–1.06)	1.05 (0.96–1.16)	1.10 (0.96–1.27)

Models adjusted for maternal age, race/ethnicity, marital status, maternal education, payer for delivery, smoking, prenatal care, parity, chronic and pregnancy associated hypertension, other fertility related condition, and infant gender
