Stillbirth Without Viability: An Intrapartum Diagnosis of Twin Reversed Arterial Perfusion (TRAP) Sequence in Monochorionic Twin Pregnancy.
Article in Cureus, 2025. 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
Twin reversed arterial perfusion (TRAP) sequence is a rare complication of monochorionic twin pregnancies, characterised by a nonviable acardiac twin perfused by a structurally normal "pump" twin. We report a case of a 33-year-old woman, G4P2012, who presented at 29 weeks in advanced labour with a history of inadequate antenatal care. She delivered a live male neonate, followed by the unexpected delivery of an intrauterine mass initially suspected to be a fibroid. Further evaluation revealed the mass to be an acardiac twin, and placental examination confirmed monochorionic diamniotic placentation, establishing the diagnosis of TRAP sequence. This case highlights the critical importance of early and detailed antenatal ultrasonography in twin pregnancies. It also raises important questions regarding the classification of stillbirths in the context of severe congenital anomalies incompatible with life.
