Pragmatic tuberculosis prevention policies for primary care in low- and middle-income countries
Bibliographic record
Abstract
Despite being a curable and preventable disease, tuberculosis is the leading cause of death from infection worldwide and is one of the top 10 causes of death from any cause, including in children [1]. Incidence is at best barely declining, increasing in some countries, and some prevalence surveys in high-burden countries have demonstrated a significantly higher tuberculosis burden than estimated [1]. Between a quarter and a third of the world's population is estimated to be infected with tuberculosis, representing a vast reservoir from which new cases arise [1]. Many of these people are never identified or tested, and even among those who are, only a small proportion receive preventive treatment [2]. Interventions that aim to increase preventive treatment uptake and completion are likely to have a greater impact on tuberculosis control and elimination than those focussing on improving completion of treatment by patients [3]. Improving tuberculosis prevention in low- and middle-income countries requires scaling up of simple policies, not better laboratory tests

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.
