IQR = interquartile range, PTH = parathyroid hormone, CTX = beta-crosslaps, BMD = bone mineral density, TBS = trabecular bone score. Data are shown as medians and interquartile range. Treatment effects with 95% confidence interval and p-values were calculated by ANCOVA for group differences at follow-up with adjustment for baseline values.
