High-Grade Atrioventricular Block and Ventricular Standstill in a Pregnant Patient.
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
Heart block during pregnancy is a rare and understudied condition that poses considerable mortality risks to both the mother and foetus. The severity of atrioventricular block (AVB) tends to worsen throughout pregnancy but may resolve postpartum in some patients, suggesting that its aetiology is linked to the haemodynamic changes of pregnancy. Management of this condition necessitates a multidisciplinary approach across cardiology, obstetrics, and anaesthetics. Pacemaker indications remain consistent with those for non-pregnant patients and can be inserted safely, particularly after the first trimester. Anaesthetists must consider the potential impacts of the Valsalva manoeuvre and neuraxial anaesthesia on maternal haemodynamics during delivery. Decisions regarding the method of delivery should be based solely on obstetric indication. This report details the case of a pregnant woman who presented with pre-syncope attributed to intermittent high-grade AVB with ventricular standstill. Transthoracic echocardiogram and cardiac magnetic resonance imaging performed during and after pregnancy, respectively, revealed a structurally normal heart. The patient was successfully treated with a leadless pacemaker, had an uncomplicated vaginal delivery and experienced no recurrence of symptoms.
