Figure 8.

Left panel: ACL development for males (black open circle) and females (shaded gray triangles) with growth curve using a fourth degree polynomial fit for males (dashed black line) and females (solid gray line). Male versus female fits are not significantly different (p=0.9). The second Y-axis reflects the percent growth for males (black, outwards tick orientation) and females (gray, inwards tick orientation). ACL is defined as the horizontal distance from the beginning of the hard palate to the intersection with the vertical line drawn from the glottis to the palatal plane. Right panel: Growth rate of ACL for males (dashed black line) and females (solid gray line) as a function of age
