Notice of Retraction: Jamal SA, et al. Effect of Nitroglycerin Ointment on Bone Density and Strength in Postmenopausal Women: A Randomized Trial.
Bibliographic record
Abstract
To the Editor We wish to retract the article “Effect of Nitroglycerin Ointment on Bone Density and Strength in Postmenopausal Women: A Randomized Trial,”1 published in the February 23, 2011, issue of JAMA. In a report issued by an investigating committee appointed by Women’s College Hospital, affiliated with the University of Toronto, to investigate, in part, the availability of data relative to this study, the committee concluded, based on objective evidence, that Dr Jamal had falsified and/or fabricated data and used that data for statistical analysis. Dr Jamal was both the first and corresponding author and was responsible for the integrity of the data and the accuracy of the data analysis. None of the other coauthors were involved in the misrepresentation of these data. All of the authors recognize the seriousness of this issue. We regret that the results of this study have been compromised and are committed to correcting the medical literature.

How this classification was reachedexpand
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.
