In the Clinical Practice Guideline Update and its Executive Summary, the new evidence was misstated. In the abstracts, “Differences from Prior Guideline,” and “General Methods and Literature Search” sections of both pieces, the new evidence was described as being from “from 1 guideline, 6 systematic reviews, 5 randomized controlled trials, and 6 observational studies”; this should have read “1 guideline, 4 systematic reviews, and 5 randomized controlled trials.”
In addition, the fourth paragraph of the Methods section of the guideline and its executive summary (“Clinical Practice Guideline” p. 5, “Executive Summary” p. 3), which describe the English-language search, only included the quality criteria for systematic reviews and omitted the quality criteria for clinical practice guidelines and randomized controlled trials. This information has been included in the revised version below. Also included is a short section, required by the National Guidelines Clearinghouse, that explicitly states that the clinical practice guideline was based on systematic reviews.
