The CINAHL Complete advanced search page offers several options for finding evidence-based practice articles. Scroll down until you see some of the options on the right.
The Evidence-Based Practice box will limit your search to Evidence-Based practice articles and journals, as well as certain types of studies.
The Randomized Controlled Trials box limits to those types of trials.
The Publication Type box has several options that might be considered strong evidence, including Clinical Trial, Systematic Review, Randomized Controlled Trial, Evidence-Based Practice and Meta Analysis.
Don't check all of these boxes or choose all these publication types at once. No articles will match all of these criteria.
In PubMed, use Article Type limiters on the left side of the page to see only specific types of articles -- Randomized Controlled Trials, Systematic Reviews, etc.

If you don't see the article type you want, click the Additional Filters at the bottom of the list and see if that article type is available.
Clinical Queries uses filters to limit retrieval to systematic reviews or research-based citations on clinical topics. The Clinical Queries link is found at the bottom of the Advanced Search screen or the PubMed home page.
Enter your search terms and evidence-filtered citations will appear under Clinical Study Categories or Systematic Reviews.
The Systematic Review feature is provided to help clinicians locate systematic reviews and similar articles. It combines your search term(s) with citations identified as systematic reviews, meta-analyses, reviews of clinical trials, evidence-based medicine, consensus development conferences, and guidelines. The resulting retrieval in PubMed Clinical Queries can be further refined using PubMed's Limits, eg, English language, humans.
