Residual Oil-Based Contrast Medium Mimicking a Metallic Foreign Body After Cesarean Section: Diagnostic Value of AI-Assisted 3D CT Analysis and Prenatal MRI.
Article in The journal of obstetrics and gynaecology research, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
A 36-year-old woman underwent an elective cesarean section at 37 weeks of gestation. A postoperative abdominal X-ray unexpectedly revealed a 20 mm hyperattenuating pelvic lesion. Computed tomography (CT) demonstrated a dense structure exceeding 3000 Hounsfield units with metallic-like artifacts, suggesting a retained metallic object. Intraoperative video review and instrument count confirmed no missing items. Three-dimensional CT reconstruction and open-source artificial intelligence (AI)-based shape analysis found no similarity to metallic instruments. Review of the patient's history revealed prior hysterosalpingography with oil-based iodinated contrast medium. Retrospective assessment of prenatal magnetic resonance imaging (MRI) showed a cystic lesion with high signal intensity on T
