Report of the International Society for Clinical Densitometry 2007 Adult Position Development Conference and Official Positions
Bibliographic record
Abstract
The International Society for Clinical Densitometry (ISCD) periodically holds Position Development Conferences (PDCs) for the purpose of establishing standards and guidelines for the assessment of skeletal health -- the nomenclature, indications, acquisition, analysis, quality control, interpretation, and reporting of bone density tests. Topics are selected for consideration according to criteria that include clinical relevancy, uncertainty in the application of medical evidence to clinical practice, and the likelihood of the expert panel achieving agreement. The most recent Adult PDC was held July 20 to 22, 2007, in Lansdowne, Virginia. Topics included technical and clinical issues relevant to dual-energy x-ray absorptiometry (DXA), vertebral fracture assessment, and bone densitometry technologies other than central DXA. This report describes the methodology and presents the results of this PDC. The first ISCD Pediatric PDC was held June 20 to 21, 2007 in Montreal, Quebec, Canada, and is reported separately.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
