Elderly	14.96 ± 3.49	6.06 ± 1.22	3.06 ± 1.35
P value young/elderly differences
Trochanteric vs. femoral neck	0.4367	0.0267	0.9560

Integral (iVOL), cortical (cVOL) and trabecular (tVOL) bone volume mean SD. Statistical significance levels for comparing young with elderly women after adjusting for height and weight are given as follows:

^aP < 0.001;

^bP < 0.01;

^cP < 0.05;

ns: P > 0.05. Statistically significant Y/E_d between TR and FN after adjusting for height and weight are in bold in the last row.
