4.Secondary Outcome
Title Change From Baseline in Mean Composite Brief Pain Inventory (BPI) Score
Hide Description Participants completed a BPI short form which is a 9 item self-administered questionnaire used to evaluate the severity of a participant's pain and the impact of this pain on the participant's daily functioning. The participant rates his or her worst, least, average, and current pain intensity, lists current treatments and perceived effectiveness, and rates the degree that pain interferes with general activity, mood, walking ability, normal work, relations with other persons, sleep, and enjoyment of life on a 10 point scale. The BPI composite score, which was calculated as the average of items 3, 4, 5 and 6 (worst pain, least pain, average pain and pain right now), ranged from 0 (best possible outcome, no pain) to 10 (worst possible outcome, pain as bad as you can imagine). A positive change from baseline indicates worsening.

8.Secondary Outcome
Title Skeletal Morbidity Rate
Hide Description An SMR for a patient was defined as the “number of occurrences” of any (or a particular) SRE allowing for only 1 event in any 3-week interval, divided by the “time at risk” in years. The “number of occurrences” and the “time at risk” were counts of SRE and the time from the randomization date. Counting began from randomization in the way that every counted event was followed by a 20-day period during which no SRE was counted, nor was the time counted as “at risk”. For example, if a patient had 1 SRE during the study, the “time at risk” was calculated as the total number of days in the study minus the 20-day follow-up period for that SRE. If a patient had no SRE events, the entire study period was counted as “time at risk”. This SMR calculation method had the advantage of avoiding multiple counts of possibly interdependent SREs (e.g. having 1 fracture increases the probability of having a subsequent SRE).

Certain Agreements
Principal Investigators are NOT employed by the organization sponsoring the study.
There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.
The terms and conditions of Novartis' agreements with its investigators may vary. However, Novartis does not prohibit any investigator from publishing. Any publications from a single-site are postponed until the publication of the pooled data (i.e., data from all sites) in the clinical trial or disclosure of trial results in their entirety.
