Abstract
Olds DL, Robinson J, O’Brien R, et al. Home visiting by paraprofessionals and by nurses: a randomized, controlled trial. Pediatrics2002 ; 110 : 486 –96 [OpenUrl][1][Abstract/FREE Full Text][2] QUESTION: Do home visits by paraprofessionals (lay visitors/peer support or community workers) trained in a programme model that is effective when delivered by nurses, improve maternal and child health? Randomised (allocation concealed), blinded (data collectors), controlled trial with follow up to 24 months postpartum. 21 antepartum clinics in Denver, Colorado, USA. 735 pregnant women (mean age 20 y) who had no previous live births and either qualified for Medicaid or had no health insurance. Follow up was >80% for maternal interviews at 6, 12, 21, and 24 months postpartum; and 83% for child assessment at 21 months of age. Participants were allocated to prenatal and postpartum (≤24 mo) home visitation by paraprofessionals (PHV group, n=245) or professional nurses (NHV group, n=235), or … [1]: {openurl}?query=rft.jtitle%253DPediatrics%26rft.stitle%253DPediatrics%26rft.aulast%253DOlds%26rft.auinit1%253DD.%2BL.%26rft.volume%253D110%26rft.issue%253D3%26rft.spage%253D486%26rft.epage%253D496%26rft.atitle%253DHome%2BVisiting%2Bby%2BParaprofessionals%2Band%2Bby%2BNurses%253A%2BA%2BRandomized%252C%2BControlled%2BTrial%26rft_id%253Dinfo%253Adoi%252F10.1542%252Fpeds.110.3.486%26rft_id%253Dinfo%253Apmid%252F12205249%26rft.genre%253Darticle%26rft_val_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Ajournal%26ctx_ver%253DZ39.88-2004%26url_ver%253DZ39.88-2004%26url_ctx_fmt%253Dinfo%253Aofi%252Ffmt%253Akev%253Amtx%253Actx [2]: /lookup/ijlink?linkType=ABST&journalCode=pediatrics&resid=110/3/486&atom=%2Febnurs%2F6%2F1%2F9.atom

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; both teacher heads agree on what is shown here.
