Denosumab Offers Relatively Lower Initial Protection Against Osteoporotic Vertebral Fractures in Treatment‐Naive Patients Compared With Zoledronate

open access: yesClinical Pharmacology &Therapeutics, Volume 120, Issue 1, Page 139-149, July 2026.
We compared the initial efficacy of denosumab (Dmab) and zoledronate (ZOL) in treatment‐naive patients with osteoporosis. This cohort study, based on TriNetX data, evaluated the risks of fractures and mortality using Kaplan–Meier survival analyses, with hazard ratios (HRs) and 95% confidence intervals (CIs).
