Search Strategy and Selection (move structure)
The methods and results of this review have been done in accordance to
the Meta-analysis Of Observational Studies in Epidemiology and Preferred
Reporting Items for Systematic reviews and Meta-Analyses (PRISMA)
statement (4,
5). The review protocol is previously
registered on the International Prospective Register of Systematic
Reviews (PROSPERO) with Centre of Reviews and Dissemination (CRD) report
number of CRD42021243598. A number of medical databases were searched
including PubMed, Ovid Medline, EMBASE, Web of Science, Cochrane Central
Register of Controlled Trials (2005-2020), Scopus, Proquest, Science
Direct and grey literature using both free-text terms and Medical
Subject Heading (MeSH) terms for studies with English language and adult
human studies that reported standardized TTE indices. The search terms
and key search strategies are listed in Supplementary Materials
1. A grey literature search identified additional studies that were not
identified in the initial search of the afore-mentioned medical
databases. All diagnostic cohort and case-control studies that measured
and compared echocardiographic parameters between myocarditis and adult
control populations were included. Studies which were not able to
provide sufficient data, those with pediatric populations or those that
did not compare the study populations involved in the analysis
hypothesis were excluded.
