A randomized controlled trial comparing two educational booklets on prostate cancer.
Bibliographic record
Abstract
PURPOSE: To compare the helpfulness of two educational aids or booklets on early-stage prostate cancer. METHOD: Participating consecutive patients and a family member, in three centres, received one of two booklets, one produced by AstraZeneca (AZ), the other produced by us (CCE); the patient and family shared a booklet but were separate study participants. The primary outcome was the Purpose-based Information Assessment completed after participants read their booklet; they rated the importance (4-point Likert scale) of six potential purposes for the information: to help organize their thoughts, understand their situations, decide on treatment, plan, provide emotional support to others, and discuss issues. Each participant then rated how helpful their booklet was (4-point Likert scale) in addressing each purpose they had rated above the lowest importance category. Participants mailed in their responses. RESULTS: Complete data were received from 308 (81%) of those who consented to the study: 152 in the CCE group and 156 in the AZ group. The CCE booklet was read for a longer time [chi(2) = 28.61, p = 0.00] but was easier to find information in chi(2) = 7.6, p = 0.05]. Although for each purpose, most readers rated each booklet in one of the top two (of four) helpfulness categories, the CCE booklet was rated more helpful for: organizing [chi(2) = 30.49, p = 0.00], understanding [chi(2) = 12.07, p = .007], deciding [chi(2) = 9.96, p = 0.02] and planning [chi(2) = 18.67, p = 0.00]. CONCLUSIONS: High helpfulness ratings of both booklets suggest that patients benefit from education aids while differences in the booklet ratings suggest that aids are not equally helpful. The CCE booklet, the more helpful booklet of this study, is a systematically developed education aid available to urologists in Canada.

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.
