Abstract
OBJECTIVE: To evaluate the best available evidence regarding the association between single-layer closure and uterine rupture. METHODS: The PubMed, Embase, and Cochrane Central Register of Controlled Trials databases were searched for relevant observational and experimental studies that included women with a previous single, low, transverse cesarean delivery who had attempted a trial of labor (TOL). The risks of uterine rupture and uterine dehiscence were assessed by pooled odds ratios (OR) calculated with a random effects model. RESULTS: Nine studies including 5810 women were reviewed. Overall, the risk of uterine rupture during TOL after a single-layer closure was not significantly different from that after a double-layer closure (OR 1.71; 95% confidence interval [CI] 0.66-4.44). However, a sensitivity analysis indicated that the risk of uterine rupture was increased after a locked single-layer closure (OR 4.96; 95% CI 2.58-9.52, P<0.001) but not after an unlocked single-layer closure (OR 0.49; 95% CI 0.21-1.16), compared with a double-layer closure. CONCLUSION: Locked but not unlocked single-layer closures were associated with a higher uterine rupture risk than double-layer closure in women attempting a TOL.

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 it
