Xpert MTB/RIF and pulmonary tuberculosis: time to delve deeper?
Bibliographic record
Abstract
I find out what the world needs, then proceed to invent it. Thomas Edison. If Edison, the world’s most prolific inventor, had to get around to creating a new diagnostic test for tuberculosis (TB), he would have considered himself pleased with the Xpert MTB/RIF test. Here is the new diagnostic test for TB that the phys-ician in the developing world has been waiting for. It does two things, and does them both well. It diagnoses TB with a higher sensitivity than a sputum smear examination: a single Xpert MTB/RIF test diagnoses 98 % of sputum smear positive cases and around 70 % of smear-negative

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.
