Abstract
BACKGROUND: There is good evidence that cancer-specific patient outreach improves rates of cervical, breast, and colorectal cancer screening. However, it is unclear how primary care practices should implement integrated outreach for all 3 types of cancer screening. We aimed to understand whether integrated outreach using mailed letters or phone calls were more effective at increasing screening uptake in a primary care organization. METHOD: test. We also compared costs per additional patient screened. All analyses were stratified by sex. RESULTS: = .073). For women and men, the letters cost approximately CaD $5.07 and CaD $7.16, respectively, for each completed screening test compared with CaD $8.71 and CaD $12.00 for the phone calls. CONCLUSIONS: Phone calls were more effective than mailed letters at increasing uptake for cervical, breast, and colorectal cancer screening among women. However, phone calls were more expensive than letters. Primary care practices should consider integrating phone call reminders into their practice, possibly as part of a targeted or staged approach to outreach for cancer screening.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
