Medical terms and Subject Heading (MeSH) terms and text words for
chronic kidney disease were combined with MeSH terms and text
words relating to clinical practice guidelines and consensus statements.
The searches were conducted in Medline (1948 to November
week 3 2011) and Embase (1980 to week 50 2011). Guideline
organizations, including the Guidelines International Network and
the National Guideline Clearinghouse, Intercollegiate Guidelines
Network (SIGN); National Collaborating Centre for Chronic Conditions
(NICE) and professional nephrology society websites were also
searched (Table S1). PLV screened the titles and abstracts and discarded
those that were ineligible. Full texts of potentially relevant
articles were obtained and examined for eligibility.
