2.1. Search strategy
A systematic review using Medline, Cochrane and Scopus databases have
been performed by March 2020, incorporating a Bayesian network
meta-analysis. A search strategy with a time interval from 1980 to 2020
was performed using the following search string for Medline (remaining
strings have been reported in Supplementary Material):
(((cabg[Title/Abstract]) OR bypass[Title/Abstract] OR cardiac
surgery[Title/Abstract] OR revascularisation[Title/Abstract] OR
revascularization[Title/Abstract])) AND
kawasaki[Title/Abstract]. The articles were screened by three
investigators (AS, JL, AM) initially by title and abstract, irrelevant
articles were excluded, and subsequently full texts were evaluated for
eligibility.
