Abstract

fetched live from OpenAlex

The systematic literature review is a powerful tool for summarizing and evaluating current knowledge related to a specific research question. Systematic reviews have many advantages over traditional narrative reviews. A meta-analysis of data from a systematic review can provide a better estimate of a treatment effect than can individual studies. To ensure quality conclusions, rigorous methods must be applied to systematic reviews, such as formulation of a specific research question, systematic literature search, selection and assessment of included studies, data extraction, quality assessment of included studies, meta-analysis and presentation of results, and formation of conclusions. Threats to the internal validity and generalizability of the conclusions of systematic reviews include lack of clarity or appropriateness of the research question, poor quality of the included studies, heterogeneity of results between studies, inappropriate conclusions, and inappropriate application in clinical practice.

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.

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.
