Study Inclusion/Exclusion

The decision criteria and process must be decided before the review begins. The review of the search results is usually conducted in two phases:
  • Review title/abstract
  • Review full-text

At least two independent reviewers are needed, with a third person available to resolve conflicts.

Keep a log of excluded studies with reasons for exclusion. Simple Excel spreadsheets can be designed to track the process.
