Description of the different stages of scoping review

Five stages of Arksey and O’Malley framework	Description of the framework adopted for this scoping review
Stage 1: identifying the research question	The research question has to be clear and broad to provide a breadth of coverage on the topic to initiate subsequent search strategies for the scoping review
Stage 2: identifying relevant studies	A comprehensive search strategy with key search phrases needs to be developed to identify relevant studies from literature, and other sources of information if required
Stage 3: study selection	Clearly defined inclusion and exclusion criteria based on the research question have to be developed for selection of studies from the search outcomes
Stage 4: charting the data	A data extraction template is developed and used to extract specific sets of data to answer the research question
Stage 5: collating, summarising and reporting results	The methods of summarising and synthesising data extracted from the studies have to be specified clearly with analytical processes used in the review to report results
