Abstract

fetched live from OpenAlex

An 85-year-old woman without recent history of surgery or trauma was referred to the emergency department (ED) by her family physician on identifying pneumoperitoneum on chest radiograph. At presentation, the patient's vital signs were stable and normal. The patient described feeling bloated with generalised mild-moderate abdominal pain, and had no respiratory concerns. On physical examination, the patient had a soft abdomen that was non-tender to percussion or palpation. There was neither rebound tenderness nor guarding and …

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

Not 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.
