Myocarditis Associated With Herpes Zoster in a 91-Year-Old Woman: A Rare Cardiac Complication With Favorable Outcomes.
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
Herpes zoster-associated myocarditis is an exceedingly rare and underreported complication of varicella-zoster virus reactivation. We describe a 91-year-old woman who developed a typical herpes zoster rash and, six days later, was admitted with clinical, laboratory, and echocardiographic evidence of acute heart failure suggestive of myocarditis. The patient improved rapidly with optimized heart failure therapy and escalation of valacyclovir, was weaned off oxygen and diuretics, and discharged in stable condition. A follow-up echocardiogram demonstrated marked recovery of left ventricular function. This case highlights the importance of recognizing rare cardiac complications of herpes zoster, such as myocarditis, and underscores the need for preventive strategies, including vaccination. Clinicians should maintain a high index of suspicion for myocarditis in patients presenting with new cardiac symptoms following herpes zoster infection.
