A team A systematic review can't be done alone! A typical team includes a project leader, a subject expert, reviewers, a methodologist and/or a librarian, and a statistician.
A research question Consider whether a systematic review is needed before starting your project. Has someone already written one on your topic? Librarians can help you find out.
A research protocol A research protocol is a detailed plan for how you will conduct your review. It is a good idea to register your protocol.
A literature search Your goal is to find ALL relevant studies on your topic, so your literature search should be thorough.
A tracking plan You’ll need to maintain detailed records of each step in the process.
Study selection and appraisal The screening of studies should be performed by at least 2 reviewers.
Data extraction The next step, also with a least 2 reviewers, is to extract data from the included studies.
Analysis and interpretation of results There are a number of tools that can help you to plot and analyze the results. The Cochrane Handbook provides detailed guidance on interpreting results and drawing conclusions.
