Abstract

fetched live from OpenAlex

The introduction of selective COX-2 inhibitors has provided a valuable treatment alternative for the management of pain and inflammation. Although selective COX-2 inhibitors have been shown to possess a significantly lower risk of serious gastrointestinal complications relative to traditional nonselective NSAIDs, the rapid uptake of these drugs have posed a small but significant risk to those individuals who may have otherwise not received any pharmacological treatment. At least one region has reported a temporally plausible increase in the rate of hospital admission for upper gastrointestinal bleeding as a result of the rapid uptake of the selective COX-2 inhibitors. Issues in understanding the clinical evidence and drug market dynamics as they relate to individuals and populations are explored in this paper along with whether or not the introduction of drugs that are safer than older alternatives can actually lead to increased population adverse event rates due to their rapid uptake.

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.
