Group	Anterolateral Ct.Th	Posterior Ct.Th
1	311.84 ± 71.47	176.15 ± 33.10
2	321.49 ± 35.97	168.85 ± 26.67

4	162.67 ± 10.53∗∗∗,###	130.37 ± 13.37

All values (µm) are expressed as mean ± sd, ANOVA followed by Bonferroni's test: ^∗∗∗ P < 0.001 versus Group 1; ^### P < 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.
