Background: The Fetal Growth Longitudinal Study (FGLS), part of the INTERGROWTH-21 st (IG-21st) Project developed major international standards for fetal size and growth. Our study aimed to formulate reference fetal biometry charts for the Egyptian population and then to compare these novel charts with those of the FGLS to ascertain the statistical...

... the polynomial terms reached significant values (all the p-values < 0.001) and the vast majority of the coefficient values were similar to the IG-21st coefficients. Again, many of the 95% CI intervals of the local curves were coherent, including the IG-21st coefficient (Tables 8-11). The local group estimated mean values (50th centiles) were on average 2% smaller for BPD and 3% and 4% larger for AC and FL respectively, as compared to the IG-21st standard. ...

... centile corresponded constantly to the 99th IG21st centile. Table 12 shows the estimated IG21st centile for the 3rd and 10th AC centile of our curve stratified for gestational age from 14 to 40 weeks. The impact of these differences on the FGR diagnosis should be very small and should result in higher sensitivity and a higher false-positive rate for FRG. ...
