Abstract

fetched live from OpenAlex

Objectives of the study were to measure recruitment rates in clinical trials and to identify patients, physicians or trials characteristics associated with higher recruitment rates. Among patients who had a clinical trial available for their cancer, 83.5% (345/413) met the eligibility criteria to at least one clinical trial. At least one trial was proposed to 33.1% (113/341) of the eligible patients and 19.7% (68/345) were recruited. Overall recruitment was 16.5% (68/413). In multivariate analyses, trial proposal and enrollment were lower for elderly patients and higher in high cancer stages. Trials from pharmaceutical industry had higher recruitment rates and trials testing hormonal therapy enrolled more patients. Breast cancer patients' accrual to a clinical trial could be improved by trying to systematically identify all eligible patients and propose a trial to those eligible and to whom the treatment is planned to be equivalent to the standard arm of the trial.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
