Change in C-terminal telopeptide cross-laps (CTX-1) median values (IQR) at 0, 3 and 12 months for both treatment groups. CTX-1 is a marker of bone resorption. The difference between the treatment groups was significant both at 3 months (p = 0.005) and 12 months (p = 0.019). 1 = baseline, 2 = 3 months, 3 = 12 months.
