Industry Funding by Itself is Not a Reason for Rating Down Studies for Risk of Bias
Bibliographic record
Abstract
To evaluate how study characteristics and methodological aspects compare based on presence or absence of industry funding, Hughes et al. conducted a systematic survey of randomized controlled trials (RCTs) published in three major medical journals. The authors found industry-funded RCTs were more likely to be blinded, post results on a clinical trials registration database (ClinicalTrials.gov), and accrue high citation counts. 1 Conversely, industry-funded trials had smaller sample sizes and more frequently used placebo as the comparator, used a surrogate as their primary outcome, and had positive results.
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 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.
