Changes in utilisation of hormone replacement therapy in Australia following publication of the findings of the Women's Health Initiative
Bibliographic record
Abstract
PURPOSE: To examine the impact of publication of the findings of the Women's Health Initiative (WHI) on the utilisation of hormone replacement therapy (HRT) in Australia with particular reference to the influence that media may have had on prescriber and consumer behaviour. METHODS: Retrospective data from the Australian Government Department of Health, Ageing DUSC Database and media hits from Factiva were reviewed to obtain prescription numbers, total cost and cost to the pharmaceutical benefits scheme and number of media hits from the year before publication of the combined HRT arm of the WHI. RESULTS: Prescribing of HRT products decreased significantly immediately following publication of the combined HRT arm of the WHI and continued to decline at a slower rate following publication of the memory and oestrogen only arms of the study. CONCLUSIONS: These results represent a more accurate national estimate of the change in HRT use in Australian women relative to previous findings from surveys carried out in Australia.

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.
