Study selection
The systematic search revealed a total of 5843 papers. After duplicates
were excluded, 3435 papers remained for review. Based on title and
abstract review, irrelevant publications for those that did not satisfy
our inclusion criteria were not considered, leaving 9
articles6,12-19 for full-text review. Following the
full-text assessment of these articles, studies that lacked data on
outcomes of FFR guided CABG, or which did not meet our inclusion
criteria were excluded (Figure 1) leaving a total of 6
articles12-17 to be analysed.
