Intrauterine Pregnancy in a Uterus Didelphys Mimicking an Ectopic Pregnancy.
Article in Cureus, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Uterus didelphys is a rare congenital uterine anomaly resulting from the complete failure of fusion of the Müllerian ducts. Early pregnancy in a duplicated uterus can present a significant diagnostic challenge, as the gravid lateralized hemi uterus may be mistaken for an adnexal mass. A 31-year-old woman presented at six weeks of gestation with mild abdominal cramping. A two-dimensional transvaginal ultrasound revealed an empty main uterine cavity and a gestational sac adjacent to the right ovary. Given a serum beta-hCG level of 4,200 mIU/mL and concern for an ectopic pregnancy, urgent diagnostic laparoscopy was performed. Surgery revealed a completely duplicated uterus, with the pregnancy confirmed to be intrauterine within the right hemi-uterus. A subsequent three-dimensional transvaginal ultrasound confirmed the diagnosis of uterus didelphys. The pregnancy progressed without complications, resulting in a planned cesarean delivery at 39 weeks due to breech presentation. Uterus didelphys can closely mimic an ectopic gestation during early ultrasound assessment. Early integration of three-dimensional transvaginal ultrasound in stable patients with suspected ectopic pregnancies is an invaluable tool to accurately identify congenital anomalies and prevent unnecessary surgical interventions.
