Myocarditis in SARS-CoV-2: A Meta-Analysis.
Review in Cureus, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
There has been a rise in cardiovascular events following the onset of the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, a strain that caused coronavirus disease 2019 (COVID-19). Although rare, there has been an increase in reports of myocarditis secondary to both individuals infected by the strain and those who received the COVID-19 mRNA vaccine. The focus of this study is to determine the risk of myocarditis associated with the COVID-19 vaccine and SARS-CoV-2 infection. Relevant literature was collected using the search engines PubMed, Google Scholar, and the WHO Global Literature on Coronavirus Disease. Randomized controlled clinical trials and cohort studies reporting the risk of myocarditis induced by SARS-CoV-2 infection and COVID-19 vaccines were used. A meta-analysis was conducted using the inverse variance method using RevMan application software. A meta-analysis of the compiled data showed a mean risk ratio of 4.74 (95% confidence interval (CI) = 2.40 to 9.36; p < 0.0000100), which indicates there is a significant difference in the risk of COVID-19-induced myocarditis in those with unspecified vaccination status compared to the non-infected population. A meta-analysis of the selected data found a mean risk ratio of 5.01 (95% CI = 4.14 to 6.08; p < 0.0000100), indicating a significant difference in the risk of COVID-19-induced myocarditis between those who are unvaccinated and the non-infected population. Upon a meta-analysis of the selected data set, a mean risk ratio of 2.55 (95% CI = 0.840 to 7.74; p = 0.100) was found, indicating no significant difference in the risk of vaccine-induced myocarditis between those with a vaccinated vaccination status and that of the non-infected population. The result of this meta-analysis showed that infection with SARS-CoV-2 in unvaccinated patients carries a statistically significant increased risk of acquiring myocarditis while those receiving the vaccination do not share this same risk.
