Cross-sectional area (CSA), compressive strength index (Compstr) and bending strength index (BSI) mean SD. Statistical significance levels for comparing young with elderly women after adjusting for height and weight are given as follows:
a
P < 0.001;
b
P < 0.01;
cP < 0.05;
ns: P > 0.05. Statistically significant Y/Ed between TR and FN after adjusting for height and weight are in bold in the last row.
