Table 4

Reduction rates of BMD between nonosteoporotic and osteoporotic groups.

		Nonosteoporotic group (-score > −2.5SD)	Osteoporotic group (-score −2.5SD)
LS		10	7
	BMD (g/[cm^2month])	0.025 ± 0.016	0.030 ± 0.020	0.600
FN		11	7
	BMD (g/[cm^2month])	0.015 ± 0.008	0.020 ± 0.009	0.272

“LS” denotes lumbar spine (L2–L4).
“FN” denotes femoral neck of the nondominant side.
“”: number of patients with BMD reduction.
: significant difference between males and females.
