Last Updated: Jun 3, 2024 3:31 PM

NEW Covidence Institutional License

The University at Buffalo Libraries are pleased to announce a new institutional license with Covidence!

Covidence is a web-based platform that streamlines the process of conducting evidence synthesis projects. With screening and data extraction tools, Covidence allows research teams to move through these stages more efficiently while tracking and documenting their progress.  

It is available to current University at Buffalo faculty, staff and students. For more information on how to sign up for Covidence, please visit our UB Covidence portal.

Evidence Synthesis Policy

This policy outlines the available assistance and possible services available from the Health Sciences Librarians at Abbott Library (HSL@Abbott) concerning systematic searches for narrative, rapid, scoping, umbrella, or systematic reviews. This service is available to those currently affiliated with the University at Buffalo (UB): current faculty, staff, residents, fellows, and/or students. Research teams must have at least one member with current UB affiliation.

Why work with us?

The HSL@Abbott librarians are trained in the systematic review process and have experience constructing searches, selecting databases, and organizing citations. The National Academy of Medicine (formerly the Institute of Medicine) recommends working with a librarian on systematic reviews, as seen below.  

From Recommended Standards for Finding and Assessing Individual Studies in Finding What Works in Health Care: Standards for Systematic Reviews

3.1.1 Work with a librarian or other information specialist trained in performing systematic reviews to plan the search strategy 

3.1.3 Use an independent librarian or other information specialist to peer review the search strategy 

Defining authorship

When librarians are part of the evidence synthesis project team, they make substantial contributions and investments of their time to the critical work of the review. As co-authors, librarians make expert contributions in the design and organization of review projects, building and translating searches across target databases, managing the exported data, utilizing the essential support tools and platforms, as well as drafting and reviewing the relevant portions of manuscripts. In doing so, librarians agree to be accountable for the quality and integrity of their work. This work is in line with authorship as described by major publishers and journal definitions of authorship: ICMJE, BMJ, Nature, CReDiT used by a number of publications from Elsevier, Wiley and Sage.   

Timeline of a Systematic Review

Don't underestimate the amount of time required for a systematic review. Most teams are balancing multiple projects and responsibilities in addition to the systematic review. The following table can help you better understand a typical length of commitment necessary for a systematic review.

Timeline of a Systematic Review
Steps General Amount of Time Needed Per Step
Protocol Development 1-2 months
Searching the Literature 1-5 months
Assessment of the Literature (Two Stages) 1-5 months
Data Collection 1-7 months
Analysis 1-3 months
Preparation of Manuscript 1-10 months
