Comparative gastrointestinal safety of bisphosphonates in primary osteoporosis: a network meta-analysis

Summary We completed a network meta-analysis of published papers to compare bisphosphonate gastrointestinal safety. We found that zoledronic acid had the highest chance of causing gastrointestinal adverse events. Etidronate had the highest chance of discontinuation due to an adverse event. No difference was found for serious adverse events.
