Abstract

fetched live from OpenAlex

We, together with the Global Burden of Disease Study and Burden of Proof (BoP) collaborators, have published a BoP Capstone Methods paper and suite of associated meta-analyses that introduce and apply a new framework for synthesizing evidence to evaluate relationships between selected risk factors and health outcomes 1 , 2 , 3 , 4 , 5 . The BoP approach was designed to address key problems in current analytical frameworks. To provide helpful information to users making decisions around risk exposure, the approach systematically estimates a flexible mean risk–outcome function, avoiding making strong assumptions such as log-linearity of the relationship. Complementing the mean risk–outcome relationship, BoP analysis provides a BoP risk function (BoPRF) that represents the lowest estimate of excess harmful risk associated with a risk factor, incorporating unexplained between-study heterogeneity after accounting for known variation in study design characteristics. From the BoPRF, we calculate summary risk–outcome scores and star-rating measures that present conservative estimates of the risk–outcome relationship and enable comparisons across different risk–outcome pairs.

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.
