Sustained Clinical Response as an Endpoint in Treatment Trials of Clostridium difficile-Associated Diarrhea
Bibliographic record
Abstract
Recurrence of diarrhea following initially successful treatmentis a major shortcoming in the treatment of Clostridium diffi-cile-associated diarrhea (CDAD). Sustained response is a clinical endpoint proposed to account for differences among treatment agents with respect to a combination of initial response/cure and recurrence. Until recently, vancomycin was the only FDA-approved treat-ment for C. difficile infection (CDI). Treatment guidelines have recommended metronidazole for a first occurrence of nonsevere CDI and for a first relapse or reinfection (2, 3, 4). Vancomycin and metronidazole are both effective in providing initial response, with85 % cure rates, but 20 to 40 % of patients whose symptoms resolve have recurrent disease caused by relapse of the original infection or reinfection from external sources (2, 3, 4). In parallel with changes in strain prevalence and severity of disease, clinical response rates have changed with metronidazole during the last

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.
