Figure 1
The flowchart shows four texts representing four stages, arranged in a vertical series on the left. From top to bottom, these are labeled “Identification”, “Screening”, “Eligibility”, and “Inclusion”. In the “Identification” stage, two text boxes are shown arranged horizontally. The text box on the left is labeled “Keyword search in electronic databases (search term: push pull mooring): Ebsco, Econbiz, Google Scholar, Jstor, Proquest, Scopus, Social Science Research Network, Web of Science: 818 studies”. The text box on the right is labeled “Review of the references of all included studies to identify additional studies: 3 studies”. From these two boxes, an arrow extends downward and points to a text box labeled “After duplicates removed: 270 studies” in the same stage. From “After duplicates removed: 270 studies”, a downward-pointing arrow leads to a text box labeled “Screening: 270 studies” in the “Screening” stage. A right-pointing arrow extends to a text box labeled “122 studies excluded: Duplicate dataset, not published in English, did not use P P M model, qualitative, wrong dependent variable, wrong method, B 2 B, geographical migration, no correlation coefficients (or similar metrics)”. From “Screening: 270 studies”, a downward arrow leads to a text box labeled “Remaining: 148 studies” in the “Eligibility” stage. A right-pointing arrow extends from this box to another text box labeled “41 studies excluded: To evaluate the conceptual framework, studies that did not report at least one correlation coefficient (or a similar metric) for the included variables were excluded”. From “Remaining: 148 studies”, a downward arrow leads to a text box labeled “Included: 107 studies” in the “Inclusion” stage.Data collection process
