Percentiles for biparietal (outer–inner) diameter, head circumference, abdominal circumference, femur length, humerus length, estimated fetal weight, femur length/head circumference ratio, and femur length/biparietal diameter ratio during gestational weeks 14–40.
The percentiles (percent) 1st, 5th, 10th, 50th, 90th, 95th, and 99th (smoothed lines) are based on quantile regression and are shown with the observed values (grey dots).

Female and male growth of estimated fetal weight during gestational weeks 14–40.
The difference in growth for female (F; red) and male (M; blue) fetuses is shown by the 5th, 50th, and 95th percentiles for EFW growth. The smoothed lines are based on quantile regression that includes data from all the participating countries.

The 10th, 50th, and 90th percentiles for estimated fetal weight in grams for the ten participating countries, with variation due to country becoming more obvious towards the end of gestation. Congo, Democratic Republic of the Congo.

Quantile–quantile plots comparing countries’ distributions with the global distribution of estimated fetal weight.
The 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles (Q05, Q10, Q25, Q50, Q75, and Q90, respectively) for the distribution of each country are plotted versus the same percentiles of the global distribution (global Q05, global Q10, global Q25, global Q50, global Q75, global Q90, respectively). Congo, Democratic Republic of the Congo.
