  1. Each group includes six rats
  2. BV/TV (bone volume/total volume) bone volume fraction, TbTh trabecular bone thickness, TbSp trabecular bone separation, TbN trabecular bone number, IQR interquartile range, Max maximum, Min minimum, OVX ovariectomy, PTH parathyroid hormone
  3. †Kruskal–Wallis test
  4. * Post hoc pairwise comparisons were conducted using Mann–Whitney exact tests with the Bonferroni adjustment; medians with the same letter (a or b) are not significantly different at the 0.0167 (0.05/3) level
