Abstract

fetched live from OpenAlex

Drug manufacturers’ reports of adverse drug events are often incomplete, lacking such basic information as the patient’s age or gender or the date of the event, a US investigation by an independent drug safety group has found. Researchers from the Institute for Safe Medication Practices looked at the quality of reports made to the US Food and Drug Administration’s Adverse Event Reporting System (FAERS) over one year to the first quarter of 2014.1 During that period 847 039 reports were made to the system, including reports of 45 688 patient deaths from US sources and 41 884 deaths from foreign sources. FAERS reports come from two main sources: from consumers or healthcare providers, who voluntarily submit reports either directly to the Food and Drug Administration (FDA) or to the drug makers; or from the drug makers, who are required by law to submit …

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.
