Abstract

fetched live from OpenAlex

This editorial discusses the role of fecal occult blood test (FOBT) in a diagnostic workup. Utility of FOBT in colorectal cancer screening is well documented in multiple clinical trials, although there continues to be a debate (and ongoing trials) on its merit relative to other screening tests. Over the years, FOBT has seen growth in its application for assessment of symptomatic gastrointestinal disease without clear guidelines on its use in this setting. The work of Lee et al. in this edition of the journal synthesizes evidence on diagnostic utility of FOBT and provides additional rationale to stop using FOBTs for symptoms evaluation or for diagnostic testing.

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.

Full frame distilled prediction

Teacher imitation

Not 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.
