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

A wide range of viral agents is associated with the development of acute myocarditis and its possible chronic sequela, dilated cardiomyopathy (DCM). There is also increasing evidence that Borrelia burgdorferi (Bb) is associated with DCM in endemic regions for Bb infection. This study sought to use electron microscopy to prospectively analyze the presence of viruses and Bb within the myocardium of 40 subjects with preserved left ventricular (LV) ejection fraction and 40 patients with new-onset unexplained DCM during the same time period. Virus particles were found within the myocardium of 23 subjects (58%) of both cohorts studied, yet there was no statistically significant difference in virus family presence between those with DCM versus those with preserved LV systolic function. In contrast, Bb was detected only in those subjects with DCM (0 versus 5 subjects; p ˂ 0.05). Polymerase chain reaction was performed on samples from patients who were positive for Bb according to electron microscopy, and Bb was confirmed in 4 out of 5 individuals. Our results demonstrate that the prevalence of viral particles does not differ between subjects with preserved LV systolic function versus those with DCM and therefore suggests that the mere presence of a viral agent within the myocardium is not sufficient to establish a clear link with the development of DCM. In contrast, the presence of Bb was found only within myocardial samples of patients with DCM; this finding supports the idea of a causal relationship between Bb infection and DCM development.
