Abstract

fetched live from OpenAlex

The inflammatory bowel diseases (IBDs) have been extensively studied with administrative databases. Ananthakrishnan et al. (this issue) used an administrative database to develop a risk score that predicted disease severity in hospitalized Crohn's disease patients. To understand the implication of this work, the concept of risk adjustment is reviewed and the advantages and disadvantages of using administrative databases to study hospitalization outcomes in IBD patients are discussed.

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.
