Bibliographic record
Abstract
Additional file 1: Table A1. Distribution of EPDS scores by cut-off among participants with depression and without depression. Table A2. Estimated sensitivity and specificity, 95% confidence intervals (CI) and CI widths for each cut-off when BREM [13] was fitted to the published and full IPD dataset. Table A3. Estimated sensitivity and specificity, 95% confidence intervals (CI) and CI widths for each cut-off when Steinhauser et al. [16] model was fitted to the published and full IPD dataset. Table A4. Estimated sensitivity and specificity, 95% confidence intervals (CI) and CI widths for each cut-off when Jones et al. [18] model is fit to the published (top) and full IPD (bottom) dataset. Table A5. Estimated sensitivity and specificity, 95% confidence intervals (CI) and CI widths for each cut-off when Hoyer and Kuss [19] model is fit to the published (top) and full IPD (bottom) dataset. Figure A1. Distribution of published EPDS cut-offs by the number of primary studies included in the meta-analyses using the published dataset. Figure A2. Distribution of EPDS scores among participants with depression (red) and without depression (blue). Purple portions are part of both the blue and red distributions. Figure A3. Estimated sensitivity (left) and specificity (right) and 95% Confidence Interval (Credible Interval for Jones et al. [18]) by cut-off for the BREM [13], Steinhauser et al. [16], Jones et al. [18] and Hoyer and Kuss [19] methods applied to the full IPD dataset. Figure A4. Estimated sensitivity (left) and specificity (right) and 95% Confidence Interval (Credible Interval for Jones et al. [18]) by cut-off for the BREM [13], Steinhauser et al. [16], Jones et al. [18] and Hoyer and Kuss [19] methods applied to the published dataset.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
