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).
