Figure 1 Accuracy of birth weight prediction with adjustment for maternal characteristics N = 313 285 Swedish births with gestational age-controlled residuals of birthweight; goodness of fit (R2) is plotted against variables added. R2 in the “optimal” middle tertile (T2) increases from 0.28 with adjustment for sex only, to 0.73 with all variables included.

Figure 4 Stillbirth (SB) rates in pregnancies with and without FGR and whether or not FGR was detected antenatally.
