1 · What the graph read from it

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.

2 · The registry

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

introductionTwin pregnancies impose greater cardiovascular demands than singleton gestations, potentially increasing long-term cardiovascular risk even in the absence of hypertensive disorders. Nevertheless, longitudinal assessments of maternal hemodynamics in uncomplicated twin pregnancies remain limited, and most available studies focus solely on the antenatal period. Chorionicity has been shown to markedly influence cardiovascular adaptation during twin gestation. This study aimed to investigate whether distinct hemodynamic adaptations occur in twin compared with singleton pregnancies during late gestation, 1 day and 6 weeks postpartum. MATERIAL AND

methodsIn this prospective longitudinal cohort study conducted at Hannover Medical School from 08/24 to 05/2025, 36 women with twin pregnancies (8 monochorionic (MC), 28 dichorionic (DC)) and 37 with singleton pregnancies underwent noninvasive hemodynamic assessment at 34 weeks' gestation, 1 day postpartum, and 6 weeks postpartum.

resultsMC twin pregnancies exhibited significantly higher cardiac output (MC: 7.72 L/min; DC: 5.62 L/min; S: 6.27 L/min; p = 0.01) and lower systemic vascular resistance (MC: 958.83 dynes × s/cm

conclusionsMonochorionic twin pregnancies are characterized by elevated cardiac output and reduced vascular resistance in late pregnancy, with a similar hemodynamic pattern appearing to persist in the postpartum period. This persistent cardiovascular strain may underlie the elevated short-term cardiovascular risk observed after twin births. Our findings highlight the need for larger longitudinal studies to explore the transition from physiological adaptation to potential cardiovascular maladaptation.
