Mean values and standard deviations (SD) for bone mineral content (vBMC.tb), epiphyseal total bone areas (Ar.tot), epiphyseal trabecular bone mineral density (vBMD.tb), diaphyseal cortical area (Ar.Ct), cross-sectional polar moment of resistance (RPol), cortical bone mineral density (vBMD.ct) and circularity (circ). p-values for sex differences are given in the bottom row. Asterisks indicate absolute significant differences from the control group: ⁎p < 0.05, ⁎⁎p < 0.01.
