Developing a search strategy for opinion and text-based evidence
This section should document how the reviewers searched for relevant papers to include in the text and opinion review. The search strategy needs to be comprehensively reported. The search strategies for all of the databases searched should be presented sequentially in the single appendix. The timeframe chosen for the search should be justified and any language restrictions stated (e.g. only studies published in English were considered for inclusion). The databases that were searched must be listed along with the search dates. Any hand searching of relevant journals should be described by journal name and years searched. Author contact, if appropriate, should also be included with the results of that contact.
