Abstract

fetched live from OpenAlex

We do not agree that immediate onset of a notably increased risk is explained by failure to adequately adjust for confounding or by reverse causation.12 Aside from matching and multivariable regression, a key reason why early risk is not just confounding is that we restricted the inclusion of studies to those done before rofecoxib was withdrawn. Confounding by indication or by contraindication is unlikely to have occurred because before September 2004 the choice of non-steroidal anti-inflammatory drug (NSAID) by …

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.
