Proč využíváme mamografii pro screening nádorů prsu a nepřestaneme ji využívat ani po vydání „aktuální“ kanadské studie?
Bibliographic record
Abstract
Clanek profesora A. B. Millera a spolupracovniků publikovaný v unoru 2014 v BMJ, který shrnuje poznatky z 25leteho sledovani v ramci Canadian National Breast Screening Study uskutecněne v prvni polovině 80. let, nepřinasi nove přesvědcive důkazy o neucinnosti mamografickeho screeningu a vyzniva velice podobně jako předchozi clanek o teto studii z roku 2000. Několik recentnich systematických přehledů potvrzuje sniženi mortality na karcinom prsu diky mamografickemu screeningu o desitky procent, odlisne výsledky teto studie mohou být dany specifickým designem teto studie a použitou mamografickou technikou. Dale je nutne upozornit, že extrapolaci výsledků letitých zahranicnich studii do podminek jineho statu nutno provadět velice opatrně.

How this classification was reachedexpand
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.
