  3. a. 12 months of treatment [53, 54, 56, 81, 82]
  4. b. 12 months of treatment [65]
  5. c. 18 months of treatment [66]
  6. d. 18 months of treatment [67]
  7. e. 12 months of treatment [68, 69]
  8. f. [71]
  9. g. Cortical volumetric BMD (Ct vBMD) as a surrogate for CtPo, Tb = Tb vBMD [83]; CtTh significant only for tibia, Tb vBMD increased at tibia [84]; Ct vBMD as a surrogate for CtPo with difference only in tibia [85, 86]
  10. h. CoPo as a surrogate for Ct vBMD, Tb as a marker of trabecular volumetric BMD (Tb vBMD) [83]; [70, 87]
  11. i. 24 months of treatment [70]; 18 months of treatment, increase in plate Tb number and thickness [88]; 18 months of treatment, increase in trabecular number [89]; 18 months of treatment, increase in CtTh in tibia only, reduction in trabecular thickness [90]
