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.
