The Efficacy of Lung Cancer Screening in Miyagi Prefecture, Japan: A Comparison of 2 Case-Control Studies Conducted in the 1980s and in the 1990s.
Bibliographic record
Abstract
1980年代と1990年代の2つの症例対照研究を較べることによって, それぞれの時代の肺癌集検の死亡リスク減少効果を比較検討した. 前期は62セット, 後期は328セットで解析を行ない, 喫煙訂正オッズ比はそれぞれ0.55, 0.54であった. 後期の対象の一部を前期のそれに類似させるとオッズ比は0.27-0.46とやや低下した. これにはSelf-selection biasと診断治療水準の向上が関与している可能性が示唆された. また, 検討した2つの研究はいずれも良好なオッズ比を示したことから, Self-selection biasがどちらの方向に影響しようが, 肺がん集検を受診することにより肺がんの死亡リスクは減少すると考えられた.

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.
