What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Placenta accreta spectrum (PAS) is an obstetric complication related to severe maternal morbidity and mortality, magnetic resonance imaging (MRI) can predict the bleeding risk and the adverse outcomes of the maternal caesarean section in PAS patients. The aim of the current study was to determine relationship of placenta area in sector 2 (S2) and cervical area measured by MRI with massive hemorrhage (MH) in complete placenta previa patients with PAS. Methods: One hundred and thirty-eight patients were diagnosed as PAS from January 2016 to December 2023 in the retrospective study. The patients were divided into two groups according to the estimated blood loss volume: MH group (estimated blood loss >2000 mL) and non-MH group (estimated blood loss ≤2000 mL). After adjusting for PAS grade and clinical variables, the correlation between placenta area in S2, cervical area and MH were evaluated with multivariate analysis. The evaluation capabilities of indicators were assessed using receiver operating characteristic (ROC) analysis. Results: The placenta area in S2 of the MH group was significantly higher than that of the group without MH ( Conclusion: The placenta area in S2 and cervical area measured by MRI show potential utility in identifying MH among patients with PAS, which may assist in preoperative risk stratification. These preliminary results require validation in future studies.
