Evaluation of Bilateral Asymmetry in the Humerus of Human Skeletal Specimen

Figure 9

This chart shows the male and female right and left mid-shaft circumference of the humerus across the geographical locations. (a) The right male humerus is thicker than the corresponding left one in all the geographical locations; r = 0.92 and p = 0.026. (b) The right female humerus is thicker than the left one in all locations except Kenya where the right is equal to the left one; r = 0.99 and p = 0.00005. The error bars represent the standard deviation of measurements for number of specimens measured (n) per geographical location.
