Table 4.

Reduction rates of BMD between nonosteoporotic and osteoporotic groups.

		Nonosteoporotic group (z-score > −2.5SD)	Osteoporotic group (z-score ≤ −2.5SD)	P
LS	n	10	7
	BMD (g/[cm2·month])	0.025 ± 0.016	0.030 ± 0.020	0.600
FN	n	11	7
	BMD (g/[cm2·month])	0.015 ± 0.008	0.020 ± 0.009	0.272

“LS” denotes lumbar spine (L2–L4).

“FN” denotes femoral neck of the nondominant side.

“n”: number of patients with BMD reduction.

P < 0.05: significant difference between males and females.
