Bone scan imprecision explains few osteoporosis device misses
Three authorized X-ray screening devices missed 49–420 people with scan-defined low bone density per 1,000 screened; scan imprecision explained at most 27.Three authorized X-ray screening devices missed 49–420 people with scan-defined low bone density per 1,000 screened; scan imprecision explained at most 27.

Who was studiedPeople in US bone-density scan data
What changedDXA imprecision explained at most 13% of cases missed by the devices at guideline-minimum precision
The catchThe modeled ceiling assumes device errors do not depend on DXA scan errors
