There are three steps in the process of gathering all of your citations into one place so you can remove the duplicates:

• Export from the database to Zotero
• Move records from Zotero to Excel
• Remove duplicates in Excel

Keep track of numbers! These will go into the PRISMA flowchart:

• The number of articles you retrieved from all of the database searches
• The number of articles you may have discovered through other methods (if any)
• The number of duplicates removed
