2.3 Inclusion and exclusion criteria
For the purpose of this review, studies concerning medical students, junior doctors, and surgical trainees were included. Whereas, those documenting non-healthcare professionals or fully-fledged CT specialists were excluded. Published randomised controlled trials, observational studies, and interventional studies investigating the knowledge, interest, skills, and attitudes in CT surgery were available for inclusion. Conference papers and editorials, literati studies with less than 20 participants, studies with only CT consultants, fellows, or CT trainees, and those not in the English language were excluded from this review. Studies that did not address our primary or secondary objectives were excluded as shown in Figure 1.
