Bibliographic record
Abstract
(2002) CMAJ 166, 21; Dennis CL, Hodnett E, Gallop R, et al. . The effect of peer support on breast-feeding duration among primiparous women: a randomized controlled trial. . Jan 8; . : . –8 . [OpenUrl][1][Abstract/FREE Full Text][2] QUESTION: Do primiparous, breastfeeding mothers who receive telephone-based peer support continue breast feeding for a longer duration than women who receive conventional care? Randomised (allocation concealed*), blinded (outcome assessors),* controlled trial with follow up at 4, 8, and 12 weeks postpartum. 2 semi-urban community hospitals near Toronto, Ontario, Canada. 258 in-hospital, primiparous, breastfeeding women who were ≥16 years of age, were able to speak English, had a singleton birth at ≥37 weeks of gestation, and were accessible by a local telephone call. Exclusion criteria were factors that could seriously interfere with breast feeding (eg, serious maternal illness or infant congenital abnormality) or prenatal enrolment with the participating volunteer breast feeding organisation. 256 women (99%) completed the trial … [1]: {openurl}?query=rft.jtitle%253DCanadian%2BMedical%2BAssociation%2BJournal%26rft.stitle%253DCMAJ%26rft.issn%253D0008-4409%26rft.aulast%253DDennis%26rft.auinit1%253DC.-L.%26rft.volume%253D166%26rft.issue%253D1%26rft.spage%253D21%26rft.epage%253D28%26rft.atitle%253DThe%2Beffect%2Bof%2Bpeer%2Bsupport%2Bon%2Bbreast-feeding%2Bduration%2Bamong%2Bprimiparous%2Bwomen%253A%2Ba%2Brandomized%2Bcontrolled%2Btrial%26rft_id%253Dinfo%253Apmid%252F11800243%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=cmaj&resid=166/1/21&atom=%2Febmed%2F7%2F5%2F156.atom

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 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, unvalidatedLabeled directly by 2 models reading the full record.
The models disagree on parts of this classification; every voice is preserved in the section at the end of the page.
