Abstract

fetched live from OpenAlex

Additional file 2: Supplementary Figures and Tables. Figure S1. Statistical power to detect associations between genetic variants and infection susceptibility at the genome-wide significance level (5e-8) when the test sensitivity is low (sensitivity = 0.7). Figure S2. Statistical power to detect a true association between a genetic variant and COVID-19 disease severity at the genome-wide significance level (5e-8). Figure S3. Statistical power to detect a true association between a genetic variant and COVID-19 disease severity at the genome-wide significance level (5e-8) when varying the case-control ratio. Table S1. Relative reduction in sample size, 1 − n test _ positive _ controls n population _ controls $$ 1-\frac{n_{test\_ positive\_ controls}}{n_{population\_ controls}} $$ , from using test-positive controls compared to population-based controls.

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.
