Briefly, the American Gastroenterological Association Institute (AGA) process for developing clinical practice guidelines incorporates Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology, and best practices as outlined by the Institute of Medicine.
Dr Steven Flamm and colleagues from Illinois, USA used GRADE methodology to prepare the background information for the guideline and the technical review that accompanies it.

The team report that optimal understanding of this guideline will be enhanced by reading applicable portions of the technical review.
The guideline panel and the authors of the technical review met face-to-face on 2016, to discuss the quality of evidence, and consider other factors relevant for the risk-benefit assessment of the recommendations.
The guideline authors subsequently formulated the recommendations.
Dr Flamm's team comments, "Although quality of evidence was a key factor in determining the strength of each recommendation, we also considered the balance between the benefit and harm of interventions, patients’ values and preferences, and resource utilization."
