[Question] how do you actually verify DEXA

Questionbranch of 10 comments

Slightly embarrassed to be asking this, but: how do you actually verify DEXA. Three scans over eighteen months, same machine, same conditions. Only the third one made the first two interpretable. On comparing yourself to composition figures from trials. Published composition data comes from supervised populations…
