Overview of systematic review methodology and key strategies for searching and reporting to the Cochrane Collaboration's Gold Standard

Heading: Report search results

Capture your search

PRISMA 2020 specifies the following as essential elements:

  1. Title of the database searched e.g. MEDLINE
  2. Name of the database platform/interface e.g. Ovid (for example, MEDLINE (Ovid), SPORTDiscus (EBSCOhost))
  3. Database date range - how many years the database covers (where stated) e.g. 1946 to present
  4. Date database last searched or consulted
  5. Years covered by the search - specify if any date limits were applied
  6. Complete search strategy (including all search terms and any limits applied)

PRISMA

'Review authors are expected to include a PRISMA-type flow diagram demonstrating the flow of studies throughout the selection process (Page et al 2021a)' -- Chapter III 'Reporting the review', Section III.3.4.1, Cochrane Handbook 2022

Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) are reporting guidelines for systematic reviews and meta-analyses. Often journals will ask your to report your systematic review results using PRISMA or another relevant reporting guideline. Find out more:
