Differentiating Diseases: The<i>Centrum</i>of Differential Diagnosis in the Evolution of Oslerian Medicine
Bibliographic record
Abstract
Pivotal to best-practice medicine in the 21st century is the concept of differential diagnosis. What the classification of disease, nosology, is to pathology, so differential diagnosis is to the management of the individual patient. Doctor-patient interaction comprises a sequence that is a six-link chain comprising history-taking; examination; differential diagnosis; tests and investigations; provisional or definitive diagnosis; and finally, management. This chain, however abridged in detail, determines every medical encounter with every patient. This paradigm has gradually evolved since the time of recorded medical history. It had developed its present form, if not its name, in Western medicine and its derivatives, with the publication of Osler's The Principles and Practice of Medicine, in 1892. The term "differential diagnosis" first appeared in the first edition of Herbert French's book, An Index of Differential Diagnosis of Main Symptoms, published in 1913.

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.
