Figure 3

Correlation between pelvic width (PW) and horizontal distance (HD, length in perpendicular line between HRC and vertical line across inferior edge of teardrop center) in the Japanese males (a) and females (b). A linear line of fit is given in each diagram (, , , and HD = 0.083 × PW + 12.657, for the males; , , , and HD = 0.091 × PW + 5.521, for the females).
