Exploring fetal fibronectin testing as a predictor of labour onset: In parturient women from isolated communities.
Bibliographic record
Abstract
OBJECTIVE: To investigate whether the fetal fibronectin assay would be useful for determining if a woman was close to a term delivery. If effective, this test would allow parturient women to stay in their communities longer. DESIGN: This feasibility study used a prospective cohort design to examine the negative predictive value of the fetal fibronectin test at term. SETTING: Iqaluit, NU. PARTICIPANTS: A total of 30 parturient women from rural and isolated communities in Nunavut. INTERVENTION: Starting at 36 weeks' gestation, women were tested every 2 days, and after 39 weeks this increased to every day until labour. MAIN OUTCOME MEASURES: The negative predictive value of the fetal fibronectin test was assessed. RESULTS: Women were no more likely to give birth at 7 or more days after their last negative fetal fibronectin test result relative to their likelihood of giving birth at 6 or fewer days after their last negative test result. Hence, the presence of fetal fibronectin in cervical secretion did not predict term delivery. CONCLUSION: This project indicated that the fetal fibronectin test did not have adequate sensitivity or specificity as a diagnostic measure to predict a delay of labour at term.

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.
