Ratings and Categories of Evidence
During the process of updating and revising the CCP Guidelines the issue of how to rate and categorize the evidence and scientific literature used resurfaced. The original panel that developed the guidelines created a Ratings and Categories of Evidence system that they felt would best allow for a clear and easily understandable method of evaluating the evidence. This clarity served the panel well and it was felt this would also best serve the end user as well as any future evaluator of the guideline’s quality since, as discussed previously, one of the attributes of a good clinical guideline has been defined as Clarity.
Other guidelines developers within the chiropractic profession have similarly developed their own ratings and category of evidence schemes.15,60,61 The CCP reviewed these schemes and felt that while they might have served those other guidelines panels, they were too unwieldy and unnecessary in light of the fact CCP was limiting its guideline recommendations to a single clinical entity – vertebral subluxation. A review of the guideline development literature found no directive that one or another rating or category of evidence scheme held more promise than another nor that there was a method that was more valid or reliable. The consensus of the literature was that some method should be used and that method should be explicitly stated.63
