Abstract

fetched live from OpenAlex

Davis and Dietrich raise important concerns about our analysis of the effect of statins in people at low risk of cardiovascular disease.1 2 On the basis of Cholesterol Treatment Trialists’ (CTT) data published in 2012,3 we showed that statins do not reduce overall mortality in people with less than a 20% 10 year risk of a major vascular event. Davis and Dietrich are correct that all cause mortality was significantly reduced in patients treated with rosuvastatin compared with controls in the JUPITER trial.4 However, the data from this study were included in the CTT meta-analysis of 2012, so singling out the all cause mortality findings from this study alone would undermine the purpose of the meta-analysis. That said, other aspects of the JUPITER trial merit consideration. At the time that the study was prematurely stopped, the number of deaths from cardiovascular causes (myocardial infarction and …

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.
