Comparison of anthropometric and metacarpal structure for 8-year-old 2a) females and 2b) males sorted into robustness tertiles. The midshaft structural data are the average of the 40, 50 and 60% sites. Data are shown as mean (standard deviation). Differences among groups were determined using a one-way ANOVA with the Tukey post hoc test. The F-statistic and degrees of freedom (dof) are included. Tertiles with different superscript letters indicate a significant difference (p < 0.05).
