Figure 1

BW percentiles (10th) by gestational age for second singleton births, total, and conditional on weight-by-gestation groups (SGA and LGA) of first births. Smoothed curve values, Norway (1967–1984). ∆: first birth LGA; ●: all second births; ○: first births SGA. The difference between the 10th percentile curves for these subgroups was 720 g at 40 weeks. The figure is modified from Figure  3 in a publication by Skjaerven and Bakketeig [20].
