Abstract
Bias and “spin” are commonplace in the reporting of trials of breast cancer treatments, a Canadian team has found. When trials failed to meet their headline objectives, authors often found positive results among the small print, and the severity of adverse effects was often understated. Authors and journals needed to do better and readers to be alert to such subtle manipulation, say Ian Tannock and colleagues from Princess Margaret Hospital in Toronto. The team searched for phase III trials of treatments of breast cancer between 1995 and 2011, finding 164 that met their criteria. They focused on the abstract—the only part of study …

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; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
