Systematic Reviews and Meta Analysis

A resource for finding data sources, filters, and standards to support systematic searches of the biomedical literature.

Software and Tools


Covidence is Web-based to for managing the review workflow. Tools for screening records, managing full-text articles, and extracting data make the process much less burdensome. Covidence currently is available for Harvard investigators with a,, or email address. To make use of Harvard's institutional account:

  1. If you don't already have a Covidence account, sign up for one at:
    Make sure you use your hms, hsph, or hsdm Harvard email address.
  2. Then associate your account with Harvard's institutional access at:
    Use the same address you used in step 1 and follow the instructions in the resulting email.
  3. To set up a project, go to your account dashboard page and click the 'Start a new review' button. Make sure you choose "Harvard University Libraries" under "which account" on the project creation page.


Rayyan is an alternative review manager that has a free option. It has ranking and sorting option lacking in Covidence but takes more time to learn. We do not provide support for Rayyan.

Other Review Software Systems

There are a number of tools available to help a team manage the systematic review process. Notable examples include Eppi-ReviewerDistillerSR, and PICO Portal. These are subscription-based services but in some cases offer a trial project. Use the Systematic Review Toolbox to explore more options.

Citation Managers

Citation managers like EndNote or Zotero can be used to collect, manage and de-duplicate bibliographic records and full-text documents but are considerable more painful to use than specialized systematic review applications. Of course, they are handy for writing up your report.
