Data extraction is difficult. You want to make it as easy as possible for your reviewers to follow the same protocol.
That’s why it’s important to create an extraction form that’s as clear as possible about how to collect and organize your data. Use tools like drop down menus, specific choices, and instructions embedded in the form to help your extractors stay on track. This is where a program like SRDR can be very useful because it includes the ability to create these kind of tools to minimize data extraction variations.
Also, be sure to frequently check in with each reviewer or have team meetings to ensure everyone is following a standardized approach.
