Abstract

fetched live from OpenAlex

Background: In search for an early and accurate assessment of graft dysfunction, a retrospective study found that low post-operative day (POD) 1 measurements of plasma Factor V in liver transplant recipients were associated with both Early Allograft Dysfunction and graft loss when stratified by a cut-off of 0.36 U/mL. Our study aimed to prospectively validate these findings and to build on the current knowledge regarding the value of Factor V as a marker for post-transplant liver function.

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.
