Tips and tricks for understanding and using SR results. No 5: Prospective Trial Registers
Bibliographic record
Abstract
Abstract This fifth article for ‘Tips and tricks for understanding and using SR results’ in Evidence‐Based Child Health is, like the previous ones, aimed at helping readers to interpret the results of systematic reviews and to use the results in clinical practice. This time, we focus on the development of (inter)national prospective trial registers and their relevance for systematic reviews. The information in this article is based on published papers on the topic and the experience of the authors in trial registration. Copyright © 2007 John Wiley & Sons, Ltd.

Full frame machine prediction
Teacher imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; the direct Gemma label and the distilled Codex classifier agree on what is shown here.
