NRSG 785: Professional Writing: Evidence Tables

Even if you have some experience with literature searching, this library guide provides guidance on how to improve a search strategy and use databases efficiently.

Module 4: Evidence Tables


In Module Four the student will explore strategies for searching the literature and the building of evidence tables. Evidence tables are developed to allow the reader to easily review a summary of a number of research studies. Additionally, the evidence table illustrates the similarities and differences between the studies reviewed. Evidence tables include the following: 1) study design, 2) sample size, 3) study findings (including statistics) 4) limitations of the study and, 5) the evidence rating including the level of the study and the quality.  The advantage of evidence tables is the ability to communicate a large amount of information in a concise clear format.


Construct an evidence table summarizing the results of the four studies chosen for the literature review. The table should include all of the required components in the template provided.


After reviewing the Literature Search Strategies Module prepared by librarians and the information about evidence tables, choose four articles for your evidence review. Construct an evidence table using the format provided in the module. Use the JHNEBP Research Evidence Appraisal tools to rate and grade your studies.
