Correlation between obstetric outcome and amniotic fluid index (AFI) in preterm prelabour rupture of membranes (PPROM)
Bibliographic record
Abstract
Background: The purpose was to determine whether AFI<5 cm after preterm premature rupture of the membranes (PPROM) is associated with an increased risk of maternal and perinatal morbidity.Methods: We performed a prospective case control study of 161 singleton pregnancies complicated by preterm prelabour rupture of the membranes (PPROM) in whom AFI was assessed. Patients were categorized in two groups on the basis of amniotic fluid index- AFI<5 cm or AFI ≥ 5 cm. Categorical data were tested for significance with the χ2 and Fisher exact tests. All 2-sided p values < 0.05 were considered significant.Results: Both groups were similar with respect to selected demographics, gestational age atrupture of the membranes, gestational age at the delivery, birth weight. Both groups were similar with respect to maternal chorio-amnionitis, abruption, mode of delivery, early onset neonatal sepsis and NICU stay. Patients with AFI<5 cm demonstrated greater frequency of C/S delivery for non-reassuring fetal tests.Conclusions: There is no significant difference between obstetric outcome in AFI<5 and AFI> 5 after PPROM between 24- and 37-weeks’ gestation.

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.
