Study Summary
Bone mineral density (BMD) measurement using dual-energy x-ray absorptiometry (DXA) is the current gold standard for osteoporosis diagnosis and therapy monitoring. Like all quantitative tests, there is some variability in BMD results obtained when scanning a person more than once. As such, it is current clinical practice, based on the recommendation of the International Society for Clinical Densitometry, that each technologist perform a precision assessment. This approach consists of scanning 30 people twice; the data from which allow determination of what constitutes a real difference in BMD with 95% confidence. A precision assessment typically evaluates a specific clinic's population, using the age range and genders seen at that clinic. However men generally have larger, but often more arthritic, bones than women which may impact the precision results. Therefore, it is possible that gender-specific precision values should be used in clinical practice, however this issue has never been investigated.
Primary Outcome
The primary analysis will compare DXA BMD precision (mean square error/variance) in males and females, pooled across technicians, using the two-sample F-test for equality of variances. Separate analyses will also be performed for each technician. In addition, due to the sensitivity of the F-test to the normality assumption, a secondary analysis will perform the same comparisons using Levene's test. A nominal two-sided p-value of 0.05 will be regarded as statistically significant.
