Searching for systematic reviews

This guide provides information on systematic review support available from UCL Library Services

Stages of a systematic review

The stages of a systematic review may vary slightly depending on the discipline and study types to be included but generally follow a series of steps outlined as follows:

  1. Clarifying the problem, defining the research question and its boundaries, and setting out criteria for studies to be included in the review. This information, along with a plan for carrying out the review, should be presented in a protocol.
  2. Searching for studies.
  3. Screening and selecting the studies, collecting and presenting the data from the studies.
  4. Appraising the relevance and quality of each study, which may involve assessing the risk of bias.
  5. Analysing and synthesising the data from the studies, which may involve a meta-analysis.
  6. Assessing reporting biases.
  7. Presenting results.
  8. Interpreting results and presenting conclusions.

Training and support available from UCL Library Services primarily focuses on the 'Searching for studies' stage of the process, but may include other stages in some circumstances.
