Hypothesis

The study aims to characterize longitudinal changes in bone microarchitecture and function in women treated with alendronate.

Conclusion

Alendronate treatment resulted in significant improvements in bone density and microarchitecture in the distal tibia compared to placebo.

Supporting Evidence

  • After 24 months of treatment, significant improvements in bone density were observed in the alendronate group.
  • Alendronate treatment was associated with a reduction in biochemical markers of bone turnover.
  • Significant differences in trabecular microarchitecture were noted between treatment and placebo groups.

Takeaway

This study looked at how a medicine called alendronate helps women with weak bones get stronger bones over two years.

Methodology

The study was a double-blind, placebo-controlled pilot study where participants underwent HR-pQCT imaging and DXA scans over 24 months.

Potential Biases

Potential selective bias due to the per-protocol analysis.

Limitations

The study had a high attrition rate and limited statistical power due to the small number of subjects completing the study.

Participant Demographics

53 early postmenopausal women aged 45-65 with low bone density.
