Abstract

fetched live from OpenAlex

Commentary on: Smyth RM, Markham C, Dowswell T. Amniotomy for shortening spontaneous labour. Cochrane Database Syst Rev 2013;6:CD006167.[OpenUrl][1][PubMed][2] Although amniotomy is one of the most commonly practiced procedures in obstetrics, there is still some controversy about its effectiveness and safety. This study by Smyth and colleagues has provided a review of the role of amniotomy alone for routinely shortening labours that start spontaneously, as well as those labours that have started spontaneously but become prolonged. Given the increase in caesarean deliveries around the world and the growing demand of women for less medical intervention in normal labour, the question of optimal labour management remains a topic of great interest. A well-conducted systematic review meta-analysis of randomised controlled trials (RCTs) of amniotomy alone versus intention to preserve the membranes was conducted. The Cochrane … [1]: {openurl}?query=rft.jtitle%253DCochrane%2BDatabase%2BSyst%2BRev%26rft.volume%253D6%26rft.spage%253DCD006167%26rft_id%253Dinfo%253Apmid%252F23780653%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/external-ref?access_num=23780653&link_type=MED&atom=%2Febmed%2F19%2F2%2F66.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.

Not 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.
