Clinical practice guidelines aim to provide optimal recommendations to help patients and healthcare professionals in shared decision-making, in consideration of systematic review and integral evaluation of the evidence and the risk–benefit balance of the medical procedure.5 The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) approach is used worldwide for developing clinical practice guidelines,6 and a manual for guideline development by the GRADE approach [Medical Information Network Distribution Service (Minds) Manual for Guideline Development 2020] is available in Japan.5 The current recommendations were made during the process of preparation of the CQs in the present Guidelines, according to the GRADE system based on an updated systematic review.
