Filling in the PRISMA flowchart

Step 1: Preparation To complete the the PRISMA diagram print out a copy of the diagram to use alongside your searches. It is most efficient to search databases individually, so print out a copy for each database searched, plus a copy for the totals. If you are using this system for a more advanced assignment, such as a thesis, ask your supervisor whether they would like you to follow this system, or to specify totals for each individual database in your final PRISMA diagram. 

Step 2: Doing the database search For each database enter each key search term individually. This should include ALL your search terms, including MeSH or CINAHL headings, truncation (like hempileg*) and wildcard (like sul?ur) search terms. 
Combine all the search terms in the different combinations using boolean operators like AND OR as appropriate. Apply all your limits (such as years of search, full-text only, English language only and so on). 
Once all search terms have been combined and you have applied all relevant limits, you should have a number of records or articles. Enter this in the top left box of the PRISMA flow chart for each database. 
If you have searched databases individually, add all the 'records identified' up and fill this total number in the PRISMA flow diagram which you will use for your coursework. 
Remember this process of adding up the number of records in individual database searches to a total will need to be repeated at each step if you search databases separately.
