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.
