[1] A prevalent fracture is defined as a fracture that a participant already had at the time of study entry. One participant had both a vertebral and non-vertebral fracture and therefore the total number of participants is higher than the baseline population number.
[2] The T-score is a comparison of a patient's bone mineral density (BMD) to that of the mean BMD for a healthy population of women at peak bone mass (30 years). A normal T-score has a value of -1.0 or higher. Osteoporosis is defined as a T-score of -2.5 or lower, meaning a bone mineral density that is two and a half standard deviations below the mean BMD of a healthy population of women at peak bone mass (30 years).

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 agreement is:
unchecked The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is less than or equal to 60 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
unchecked Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed.


Limitations and Caveats
Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
