Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Zoledronic Acid and Placebo to Risedronate | Participants received zoledronic acid 5 mg intravenous infusion one dose, 60 days of oral placebo to risedronate, calcium 500 mg twice a day and vitamin D 400 to 1000 international units daily during the core period, and received only calcium and vitamin D supplements during the extended observation period. | 8 | 75 | OG000 |
| Group 2 | Risedronate and Placebo to Zoledronic Acid | Participants received 60 days of oral risedronate 30 mg, one intravenous infusion of placebo to zoledronic acid, calcium 500 mg twice a day and vitamin D 400 to 1000 international units daily during the core period, and received only calcium and vitamin D supplements during the extended observation period. | 29 | 52 | OG001 |
