Fig 1. Adjusted odds ratios and 95% CI for the risk of sponta-neous preterm delivery using either neonatal (horizontal barsfilled with diagonal lines) or fetal (open horizontal bars) growth stan-dards in the 4 fetal growth categories. The appropriate for gesta-tional age group was used as the reference standard. FGR, Fetalgrowth restriction (group); bFGR, borderline fetal growth re-striction (group); bLGA, borderline large for gestational age(group); and LGA, large for gestational age (group).
