Use of dual-energy x-ray absorptiometry in body-composition studies: not yet a “gold standard”
Open accessAbstract
The advent of dual-energy x-ray absorptiometry (DEXA) has greatly improved the precision and accuracy of bone-mineral density determinations in research and in clinical practice (1). Because the current generation of DEXA machines can also identify soft tissue and categorize it as fat or lean, there has been a great deal of interest in using DEXA for measurement of these compartments as well. At several conferences we have now heard the conclusion that DEXA is a ‘ ‘gold standard’ ‘ for body-composition research involving noncalcified tissues, and not solely for bone-density research. We suggest that caution be used before DEXA be adopted uncritically for this purpose.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
