Where Do I Find Primary Studies to Include in a Systematic Review?

  • Cumulative Index to Nursing and Allied Health Literature (CINAHL) is a database that covers nursing and allied health disciplines, including health administration. 
  • PubMed/ MEDLINE is the National Library of Medicine's biosciences database covering medicine, nursing, dentistry, veterinary medicine, health care systems, and preclinical sciences.  The Health Sciences Library provides access to PubMed and multiple MEDLINE interfaces. 
  • Web of Science (Science Citation Index and Social Science Citation Index) SCI covers medical and life sciences, and other sciences. SSCI includes economics, education, health sciences, social policy and social work.

NOTE: Logging in to the following databases through the Health Sciences Library Databases ensures you have access to the full text of articles, when available.

Some systematic review topics will be covered by subject specific databases.

Freely available databases such as AGRICOLA (agriculture, including animal sciences, human nutrition, environmental sciences and more); Basic Medical Sciences Databases; ERIC (education); PEDro (physiotherapy) and others may be appropriate depending on your topic. A database not available to affiliates of New York Medical College can be searched by a librarian through Dialog for associated fees. 

Resources to Guide you in Conducting a Systematic Review

Where Do I Find Systematic Reviews?

  • The Campbell Collaboration is an international research network that produces systematic reviews of the effects of social interventions focusing on education, crime and justice, and social welfare.
  • The Centre for Reviews and Dissemination (CRD) databases are updated daily and provide decision-makers with access to quality assessed systematic reviews, economic evaluations, summaries of health technology assessments, summaries of all Cochrane reviews and protocols, and summaries of Campbell reviews.
  • The Cochrane Database of Systematic Reviews (CDSR) includes the full text of regularly updated systematic reviews of the effects of healthcare prepared by The Cochrane Collaboration.
  • The Database of Abstracts of Reviews of Effects (DARE) covers a broad range of health related interventions and complements the CDSR by quality-assessing and summarizing reviews that have not yet been carried out by the Cochrane Collaboration. Each abstract includes a summary of the review together with a critical commentary about the overall quality.
  • Both PubMed and PubMed Clinical Queries can be used to locate systematic reviews. The Clinical Queries tool retrieves citations identified as systematic reviews, meta-analyses, reviews of clinical trials, evidence-based medicine, consensus development conferences, guidelines, and citations to articles from journals specializing in review studies of value to clinicians.

NOTE: Linking to the Cochrane Databases and PubMed through the Health Sciences Library ensures that you have access to the full text of systematic reviews and articles when available.

Tools for Screening and Selection

 

In your protocol you have already established the eligibility criteria for inclusion. In other words, what does the study need to look like in order to answer your research question? What is the population? Age? Time frame? Problem? Intervention?

Since you have cast a wide net and completed a rigorous search, you have many studies from which to choose. You will now use this criteria for screening and selecting.

Remember, screening and selection requires two or more reviewers to work independently from one another. This reduces any chance of bias.

Here are two tools that may help in this process. Keep in mind, Covidence goes beyond the initial screening process and into selecting, it also allows you to extract the data. 

Rayyan QCRI

Rayyan is similar to Covidence but less costly. It too is a web-tool that dramatically speeds up the process of sorting and screening.  Unlike Covidence it is free, but also unlike Covidence, Rayyan does not go beyond the screening process to the selection or data extraction phase. Covidence does.

Covidence is a web based tool that streamlines your ability to screen, select, as well as extract the data from the selected studies for your systematic review.   It can also Generate this PRISMA flow diagram and can export quality assessment, risk of bias, and study data to RevMan to generate reports and MetaAnalysis.​

Outside of the free trial though, Covidence is fee based. 

 

Exporting studies From Covidence to:

Review Manager (RevMan)

When you have completed the data extraction in Covidence for each included study, you are now ready to export your data to RevMan Web

Here is a link for more information.

RevMan facilitates preparation of protocols and full reviews, including text, characteristics of studies, comparison tables, and study data. It can perform meta-analysis of the data entered, and present the results graphically.
