Abstract

fetched live from OpenAlex

Is pneumococcal vaccination effective for various clinical outcomes in adults? Included studies compared pneumococcal polysaccharide vaccine with placebo, other vaccines, or no intervention (control). Studies of children; evaluation of antibody responses only or pneumococcal polysaccharide vaccines as a booster after conjugate pneumococcal vaccine; or animal, laboratory, and observational intervention studies were excluded. Outcomes were definitive pneumococcal pneumonia, presumptive pneumococcal pneumonia, all-cause pneumonia, bacteraemia or invasive pneumococcal disease, bronchitis, all-cause mortality, pneumonia mortality, and mortality from pneumococcal infection. Medline (1966 to May 2007), EMBASE/Excerpta Medica (1974 to May 2007), Cochrane Central Register of Controlled Trials, Latin American and …

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.

Direct model labels (unvalidated)

Per-model category and study-design labels from the labeling rounds. They are machine output, unvalidated, and the disagreement between models ships as data. No study design here is MEDLINE-validated yet.

Full frame distilled prediction

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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.
