		3 wk	6 wk	12 wk	24 wk
Bone	ΔDSH	0.23 ± 0.28	0.41 ± 0.35	0.54 ± 0.48	0.75 ± 0.45
	P	0.1057	0.0349	0.0397	0.0098
Cage	ΔDSH	0.00 ± 0.32	0.51 ± 0.72	0.51 ± 0.35	0.07 ± 0.81
	P	0.9806	0.1448	0.0151	0.8364

ΔDSH refers to the variation of DSH and positive value indicates the decrease of DSH. Statistically significant differences during period ( = 0.05) are marked by boldface text (paired t-test).
