Abstract
Abstract Background Some studies have indicated a notable association between obesity and placenta accreta spectrum (PAS), while others have not reported. Hence, we performed a meta-analysis to explore the association between obesity and the risk of PAS. Methods To explore the association between obesity and PAS through observational studies, we conducted a systematic search across PubMed, Web of Science, Google scholar, and Scopus databases up to March 30, 2024. The meta-analysis utilized a random-effect model, with the quality of included studies assessed using the Newcastle–Ottawa scale. A significance level of less than 0.05 was considered statistically significant using Stata software, version 14 (StataCorp, College Station, TX, USA). Results The association between obesity and PAS risk in crude studies showed significance (1.51 [95% CI: 1.19, 1.82; I 2 = 0.0%]). However, in adjusted studies, the association was not significant (1.25 [95% CI: 0.45, 2.05; I 2 = 52.0%]). Conclusion These findings suggest that obesity has been proposed as potentially associated with a higher risk of PAS, particularly evident in crude studies. However, it is imperative to conduct prospective cohort studies with a large sample size and meticulous control of confounding variables to further elucidate this relationship.

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
