A systematic review is defined as “a review of the evidence on a clearly formulated question that uses systematic and explicit methods to identify, select and critically appraise relevant primary research, and to extract and analyze data from the studies that are included in the review.” The methods used must be reproducible and transparent.

Choosing a Review Type: This guide explains other comprehensive literature reviews of similar methodology to the systematic review.
Here is a helpful article about review types. (Meeting the Review Family: Exploring review types and associated information retrieval requirements, 2019,Sutton et al.)
1. Gathering your team (Minimum of two reviewers with a third to serve as a tiebreaker)
2. Questioning (Define a narrow question, may use PICO) Is your review question a complex intervention? Learn more here.
3. Planning (Create a priori protocol (See Prisma-P extension), plan/test search strategy, register protocol (PROSPERO-see below)
4. Searching/Screening (Exhaustive, transparent & repeatable searching for evidence/selecting studies) Includes database, grey literature/clinical trial registry and handsearching of the literature. Screening is done in two phases. The first phase is screening titles/abstracts, the second phase is screening full texts. Screening is done independently by two reviewers, with a third as a tiebreaker.
See our Systematic Review Search Service for help conducting the search!
5. Managing & reporting (all methods are transparent and reproducible)
