• The ground analog that fits bone better than muscle — head-down bed rest as a readout-dependent model of spaceflight musculoskeletal loss, and how matching the instruments inverted the field's working assumption

• The Stavnichuk and Böcker spaceflight bone-loss figures are not interchangeable: pooled multi-method bone density versus single-instrument volumetric content

• The Böcker matched spaceflight/bed-rest comparison is site- and instrument-matched but not duration-matched, with spaceflight roughly three times longer than the bed-rest arm
