The vertical flowchart enclosed within a rectangular boundary that illustrates a five-stage process. On the left side, labels “Stage 1”, “Stage 2”, “Stage 3”, “Stage 4”, and “Stage 5” appear, each with a rightward arrow pointing to a rectangular box. In Stage 1, the arrow points to a box labeled “Define the Research Questions”, which contains the text “Determine the review aim” and “Formulate research question”. A downward arrow from this box points to the Stage 2 box labeled “Formulate Review Protocol”, which contains the text “Identify keywords” and “Database identification”. A downward arrow from this box points to the Stage 3 box labeled “Review Literature”, which contains the text “Search database” and “Screen search results against standards”. A downward arrow from this box points to the Stage 4 box labeled “Extract Literature”, which contains the text “Structure the summary literature” and “Extract relevant information”. A downward arrow from this box points to the Stage 5 box labeled “Synthesis Finding”, which contains the text “Descriptive quantitative analysis” and “Qualitative literature synthesis”. At the bottom of the diagram, the text reads “Source(s): Adapted from Pickering and Byrne (2014)”.Systematic literature review process
