Literature Search and design
The review team developed the literature search strategy. Studies
related to the subject were identified by searching electronic databases
and bibliographic reference lists of relevant articles. An electronic
search in PubMed/Medline, EMBASE, Scopus, and Web of Science databases
was conducted from their beginning to June 2020 to identify studies
reporting the outcomes of FET procedure in cohorts of patients diagnosed
with ATAAD. A combination of controlled vocabulary and free text terms
(utilizing Boolean operators) was used to interrogate the databases. The
search was limited to English-language articles and human studies. The
search strategy is presented in supplementary table 1. The present study
is conducted and reported following the Preferred Reporting Items for
Systematic reviews and Meta-Analyses (PRISMA) guidelines (8).
