Static histomorphometric parameters of trabecular bone in L5 vertebral body sections.

Group	BV/TV (%)	Tb.Th (µm)	Tb.N (/mm)	Tb.Sp (µm)
1	24.54 ± 2.28	59.56 ± 3.14	4.14 ± 0.54	185.12 ± 28.70
2	23.35 ± 2.31	53.29 ± 2.28	4.39 ± 0.52	180.33 ± 26.25
3	14.97 ± 3.55	50.75 ± 6.50	2.93 ± 0.41	298.79 ± 53.81
4	14.36 ± 0.73	47.07 ± 2.12	3.03 ± 0.06	285.34 ± 11.12

All values are expressed as mean ± sd, ANOVA followed by Bonferroni’s test: < 0.05, < 0.01 versus Group 1; < 0.001 versus Group 2. Group 1: baseline; Group 2: control, normal diet; Group 3: calcium-deprived diet for 4 weeks; Group 4: calcium-deprived diet, plus concomitant administration of PTH (1-34) 40 µg/kg/day, for 4 weeks.
