Abstract

fetched live from OpenAlex

OBJECTIVES: To provide reference expected cumulative survival tables, reducing steps in the calculation of mortality ratios and excess death rates from the medical literature, when source data are in terms of survival curves or cumulative survival rates. METHOD: Actuarial methodology. RESULTS: Tables provide cumulative expected survival rates calculated by entry age and for different periods of follow-up, as used in clinical trials and registries in the medical literature. CONCLUSION: The observed survival in scientific papers can be appraised promptly using cumulative survival tables calculated from either insurance or population life tables.

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.
