Composition and nanomechanics connecting letters report. Parameter means (A) and distribution widths (B) for compositional (mineral-to-matrix ratio, MM; collagen maturity, XLR; and crystallinity, XST) and nanomechanical (reduced modulus E; hardness H) parameters, showing all significant pairwise differences between individual groups. Data are shown raw (not age-adjusted). Uppercase letters represent P < 0.05 and lowercase letters represent P < 0.10 (not significant) by Mann–Whitney U test.
