When to perform gastroscopy in the PSC patient
Bibliographic record
Abstract
Variceal hemorrhage (VH), particularly from esophageal varices, is associated with high fatality and recurrence rates in cirrhotics despite standard medical and endoscopic intervention.1 In primary sclerosing cholangitis (PSC), the decision to perform screening endoscopy varies. Retrospective studies suggest that platelet count negatively correlates with endoscopic features of portal hypertension,2,3 but assessment of the strength of this association requires further observational data as it is based on a relatively small number of patients with PSC. To further assess the relationship between platelet count and the presence of large (> 5 mm) esophageal varices in patients with PSC, and to determine the association between liver enzymes and model for end-stage liver disease score (MELD) with risk for large esophageal varices, we assessed all adult PSC patients seen at the University of Western Ontario over a 10 year period following approval by the Ethics Review Board. Baseline clinico-demographic and endoscopic data on presence and grade of esophageal varices were collected and summarized in table 1 on the 66 patients that fulfilled criteria. Univariate logistic regression analysis was conThe Official Journal of the Mexican Association of Hepatology, the Latin-American Association for Study of the Liver and the Canadian Association for the Study of the Liver

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
