CINAHL contains Evidence-Based Care Sheets for various diseases and conditions that can be a great way to get a head-start on gathering the best evidence for medical decision-making. You can see this as a "Source Type" limiter on the left after performing a search, OR, you can search them directly by clicking the Evidence-Based Care Sheets link at the top of CINAHL's landing page. Here's an example image:

At the end of each page is a list of the sources that constitute the evidence upon which this sheet is based. Each item is coded according to a Coding Matrix, which is another way of looking at the pyramid listed below. Note that the evidence levels are listed in order from strongest (Published Meta-Analysis) to weakest (Conference proceedings, abstracts, presentation).
