The Work Group has critically reviewed the feedback from the public input and revised the guideline as appropriate for the nal publication. We thank Alfred K. Cheung, MD and Johannes F.E. Mann, MD for leading this important initiative, and we are especially grateful to the Work Group members who provided their time and expertise to this endeavor. In addition, this Work Group was ably assisted by colleagues from the independent Evidence Review Team (ERT) led by Jonathan Craig, MBChB, DipCH, FRACP, M Med (Clin Epi), PhD; Martin Howell, PhD; and David Tunnicliffe, PhD, who made this guideline possible. KDIGO recently appointed Marcello Tonelli, MD, SM, MSc, FRCPC as its rst Guideline Methods Chair. He was tasked with improving KDIGO guideline methodology by reinforcing the linkage between the recommendations and the corresponding evidence, standardizing the guideline format, reducing unnecessary length, and enhancing the utility of the guideline for its users. To meet these goals, Dr. Tonelli suggested KDIGO work with MAGICapp, a web-based publishing platform for evidence-based guidelines. The program uses a prede ned format and allows for both direct linkage of the evidence to the recommendation statement, and the generation of patient decision aids directly from the evidence syntheses used to support the guideline. In addition, he also introduced the concept of practice points, a new form of guidance in addi- tion to recommendations. For cases in which a systematic review was not done, or was performed but did not nd suf cient evidence to warrant a recommendation, a practice point was used to provide guidance to clinicians. Practice points do not necessarily follow the same format as recom- mendations for example, they may be formatted as tables, gures, or algorithms and are not graded for strength or evidence quality.
