This guide explores advanced searching techniques in CINAHL Plus with Full Text (the Cumulative Index to Allied Health Literature).

General Strategies

There is no one way to limit to quantitative studies in CINAHL, but there are several strategies to try. Be sure to review the methods of the studies you find to be sure that they are quantitative. Look for the following:

  • Statistics
  • Charts and Graphs
  • Design, Methods, Results, Discussion, or Conclusion section

Quantitative studies is a subject heading in CINAHL. Enter quantitative studies into the search box, along with your topic keywords, and change the drop-down menu to ‘MH Exact Subject Heading.’ This may not retrieve all of the quantitative studies available, but it is one strategy to use.


Limit your search to Randomized Controlled Trials.  Enter your topic and set limiters for Randomized Controlled Trial.



Limit your search by Publication Type to those that are likely to include quantitative methods such as: Clinical Trial, RCT, Meta-Analysis, Statistics,Tables/Charts. Be sure to review the methods of the articles you find to ensure they are quantitative.
