Search Results
The initial literature search yielded 1276 studies from various literature sources, including grey literature. After removing duplicates, 1058 records were screened by title and abstract of which 558 studies were initially excluded, as they included non-myocarditis populations or were in supplementary format. The remaining 500 records were reviewed by title and abstract screening by two reviewers (SK and AA). A total of 110 peer-reviewed studies were assessed by full text for eligibility of which 14 studies were shortlisted for inclusion in this study. Studies that did not have a direct comparison between myocarditis patients and controls, those that included pediatric populations and those that did not report results as means and standard deviations were excluded (n=8). Data from 6 studies with publication dates ranging from Jan 2010–Jan2020 was extracted and meta-analyzed, and is shown inTable 1. A detailed flow diagram with the study selection process and various reasons for exclusion is shown in Figure 2.
