Table 3.
Development of trabecular architectural variables is comparable across regions, sexes and bones, i.e. age categories have the same structure assessed using one-way anova with Tukey’s post-hoc. Abbreviations denote: Tb.Th, trabecular thickness; Tb.N, trabecular number; BV/TV, bone volume fraction. Grey text indicates non-significant difference in architecture.
