Reproducibility of bone variables at the 4% distal tibia (mean ± SEM)

Variable	Premenopausal subjects (n = 7)	Postmenopausal subjects (n = 8)	All subjects (n = 15)	rmsCV (%)(n = 15)
Density (mg/cm³)
TOT_DEN	317 ± 10.3	267 ± 12.6^*	290 ± 10.4	1.5
TRAB_DEN	241 ± 8.3	203 ± 7.6^**	221 ± 7.4	1.6
Mass (mg)
TOT_CNT	317 ± 20.0	273 ± 16.6	294 ± 13.8	1.6
TRAB_CNT	109 ± 7.0	94.0 ± 5.7	101 ± 4.7	4.3
Area (mm²)
TOT_A	1001 ± 54.0	1024 ± 42.5	1013 ± 32.7	2.8

rmsCV = root mean square coefficient of variation; SEM = standard error of the mean; TOT_A = total area; TOT_CNT = total content; TOT_DEN = total density; TRAB_CNT = trabecular content; TRAB_DEN = trabecular density.
