2.2 Data Extraction
The result of the literature search retrieved 793 studies for screening
process. After duplicates were removed using EndNote 7 software, 358
records were retrieved for initial screening. The primary checking of
the abstracts produced 45 studies addressing CABG patients. After
examination of full-text articles, 8 eligible studies were finally
included in the literature review, after excluding articles that
concentrate on the effect of psychological interventions. The full text
of articles was examined based on the title first for suitability, then
the abstract of the studies was reviewed, then full text. Outcomes
measured other than those stated in the inclusion criteria also
excluded. Thus, eight studies were considered in the review. Figure. 1
