Note: between the three age groups of 16–18, 19–21, and 22–25 weeks, the means marked by letters (a), (b), and (c) in every column differ significantly: for transverse diameter: (a) versus (b) p < 0.001, (a) versus (c) p < 0.001, and (b) versus (c) p < 0.001; for sagittal diameter: (a) versus (b) p < 0.001, (a) versus (c) p < 0.001, and (b) versus (c) p < 0.001; for height: (a) versus (b) p < 0.01, (a) versus (c) p < 0.001, and (b) versus (c) p < 0.001; for base circumference: (a) versus (b) p < 0.001, (a) versus (c) p < 0.001, and (b) versus (c) p < 0.001; for length of anterior margin: (a) versus (b) p < 0.001, (a) versus (c) p < 0.001, and (b) versus (c) p < 0.001; for length of posterior margin: (a) versus (b) p < 0.01, (a) versus (c) p < 0.001, and (b) versus (c) p < 0.001.
