Abstract
OBJECTIVES: From the Canadian Registry of patients with Upper Gastrointestinal Bleeding and Endoscopy (RUGBE), we determined clinical outcomes and explored the roles of endoscopic and pharmacologic therapies in a contemporary real-life setting. METHODS: Analysis of randomly selected patients endoscoped for nonvariceal upper gastrointestinal bleeding at 18 community and tertiary care institutions between 1999 and 2002. Covariates and outcomes were defined a priori and 30-day follow-up obtained. Logistic regression models identified predictors of outcomes. RESULTS: One thousand eight-hundred and sixty-nine patients were included (66 +/- 17 yr, 38% female, 2.5 +/- 1.6 comorbid conditions, hemoglobin, 96 +/- 27 g/L, 54% received a mean of 2.9 +/- 1.7 units of blood). Endoscopy was performed within 24 h in 76%, with ulcers (55%) most commonly noted. High-risk endoscopic stigmata and endoscopic therapy were reported in 37%. Rebleeding, surgery, and mortality rates were 14.1%, 6.5%, and 5.4%, respectively. Decreased rebleeding was significantly and independently associated with PPI use (85% of patients, mean daily dose 56 +/- 53 mg) in all patients regardless of endoscopic stigmata, (odds ratio (OR):0.53, 95% confidence interval, 95% CI:0.37-0.77) and endoscopic hemostasis in patients with high-risk stigmata (OR:0.39, 95% CI:0.25-0.61). PPI use (OR:0.18, 95% CI:0.04-0.80) and endoscopic therapy (OR:0.31, 95% CI:0.11-0.91) were also each independently associated with decreased mortality in patients with high-risk stigmata. CONCLUSIONS: These results appear to confirm the protective role of endoscopic therapy in patients with high-risk stigmata, and suggest that acute use of PPIs may be associated with a reduction of rebleeding in all patients, and lower mortality in patients with high-risk stigmata. Independent prospective validation of these observational findings is now required.

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 it
