Abstract

fetched live from OpenAlex

La llegada de nuevos medicamentos al mercado exige muchos años de investigación previa junto con la evaluación continua de sus resultados durante toda la vida del medicamento. Ello justifica la necesidad de la investigación farmacoepidemiológica, entendida como el estudio del uso y los efectos de los medicamentos en grandes poblaciones. En la actualidad, este tipo de investigación parece más factible que nunca, habida cuenta de la expansión que han experimentado de las fuentes de información por la incorporación masiva de datos, (por ejemplo, registros clínicos de pacientes o historia clínica electrónica). No obstante, ante el entusiasmo que suscita el “Big Data”, se debe tener en cuenta el riesgo de sobreinformación, de evidencia fragmentada y que su naturaleza mayoritariamente observacional está sujeta a sesgos y confusión. La utilización de los métodos epidemiológicos en este escenario se antoja fundamental para su análisis. En definitiva, el manejo y aprovechamiento de estas fuentes de información en expansión para generar información útil constituye el próximo desafío para la aplicación de los métodos de investigación en la farmacoepidemiología moderna.

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.
