Influenza A-Induced Myocarditis and Persistent Complete Heart Block in Pregnancy.
Article in Cureus, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Cardiovascular implications of respiratory viruses are often overlooked. Arrhythmia is a rare manifestation of influenza A and is usually self-terminating after the acute phase. Only a handful of cases of complete heart block (CHB) associated with influenza A have been reported. We present the case of a healthy 33-year-old primigravida who developed CHB at 20 weeks' gestation after contracting influenza A, requiring hospitalisation. Thereafter, the patient remained asymptomatic throughout the prepartum period despite persisting CHB and bradycardic escape rhythm. Delivery was successfully managed with spinal anaesthesia and close haemodynamic monitoring. Postpartum cardiac imaging confirmed myocarditis. CHB with a narrow escape rhythm persisted after delivery. The emergence of symptoms and a blunted heart rate response to exercise necessitated elective permanent pacemaker (PPM) implantation after careful consideration. This case underscores the importance of cardiac evaluation in pregnancy, particularly after seasonal influenza, and highlights the challenges in diagnosing and managing CHB within this context.
