Abstract

fetched live from OpenAlex

We thank M. Ekström and colleagues for their interest in our study [1] and for their comments. The central concepts that M. Ekström and colleagues express in their correspondence are that our findings of increased respiratory-related morbidity and mortality in association with new serotonergic antidepressant use among older adults with chronic obstructive pulmonary disease (COPD) “likely reflect the underlying illness(es) and other unmeasured factors rather than an actual drug effect”. Propensity score matching and stratification are methods that help minimise the risk of confounding and misattribution in observational studies

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.
