What was measured

Time to the first-and-subsequent on-study skeletal-related event (SRE), analyzed for superiority of denosumab using multiple event analysis, the event must occur at least 21 days after the previous SRE. This outcome measure utilizes multiple event times, was analyzed based on a proportional mean model, and is therefore more appropriately summarized by the cumulative mean number of events.
