Abstract
Introduction: The Risk Of Bias in Non-randomized Studies – of Interventions (ROBINS-I) tool evaluates internal validity (risk of bias) in non-randomized studies of interventions in comparison to an ideal (hypothetical) randomized trial. The use of ROBINS-I in studies dealing with exposures or interventions in environmental health has not yet been explored. This study evaluated the usability and applicability of ROBINS-I in studies of environmental health (EH) exposure. Methods: Three researchers in sequential rounds applied ROBINS-I to three systematic reviews of EH exposures: bisphenol-A and obesity; perfluorooctanoic acid and birth weight; and polybrominated diphenyl ethers and thyroid function. We began by providing instructions for application of ROBINS-I to EH studies, including possible confounders and co-exposures specific to the exposures considered in the three reviews. For the first two rounds of testing, two reviewers independently applied ROBINS-I and provided feedback on usability of the tool. Barriers and facilitators to the appropriateness of ROBINS-I for environmental health were identified and modifications made to the tool, as necessary. For the third round of testing, three reviewers independently applied the tool and came to consensus on item-level and overall study risk of bias. Results: Suggested modifications ranged from syntax and wording to conceptual changes to the tool. The term “intervention” was replaced with “exposure” throughout the document. Additional instructions were provided to address assessment of cross-sectional studies. Fields to collect information on measurement of exposures and outcomes of interest was added to the project protocol. Additional granularity was added to the measurement of interventions/exposure domain. Conclusion: Modifications made to the risk of bias tool to tailor it to studies of EH exposure increased understanding and application of the tool, as well as consistency in responses.

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 imitationNot 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.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
