Clinical practice guidelines
The guidelines were developed following the GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) method (Supplemental Table S1).5 The primary target audience for these guidelines is surgeons providing care to children with WT, particularly in settings with limited resources. The recommendations are also intended to be used by policymakers and senior managers as the basis for developing national and local WT protocols and policies and for supporting staff education and training.
