The reproducibility of DEXA scores is frequently reported at 1-2 percent. That 1-2 percent is the average, but the range of reproducibility can vary as much as 7 percent. Variations come from changes in machine reading (using the same machine), technologists who are doing the test, and slight changes and body positioning, | The reproducibility of DEXA scores is frequently reported at 1-2 percent.

- | The Danish epidemiologist Brot studied 500 healthy women ( that is they were not drawn from a population with particular health issues) aged 42 to 58 and concluded that in this group bone density was strongly inversely proportional to 1,25 D levels ( that is low bone density was strongly associated with high 1,25 D levels) and only rather weakly directly proportional to 25 D levels. The sample was chosen randomly - and was not done to test the impact of any particular treatment programme. | + | The Danish epidemiologist Brot studied 500 healthy women ( that is they were not drawn from a population with particular health issues) aged 42 to 58 and concluded that in this group bone density was strongly inversely proportional to 1,25 D levels ( that is low bone density was strongly associated with high 1,25 D levels) and only rather weakly directly proportional to 25 D levels.
