“…GRADE Grading of Recommendations Assessment, Development and Evaluation, RCT randomized controlled trial, GRADE-ADOLOPMENT GRADE Evidence to Decision frameworks for adoption, adaptation, and de novo development of trustworthy recommendations documents applied the GRADE approach for grading the certainty of evidence for PEN-related outcomes (for instance, increase of physical activity, change of body-mass index (BMI), and sugar or salt intake) (see Table 3). The remaining 14 documents were either systematic review protocols (n = 8, [26,33,35,36,40,44,48,50]) where GRADE will be used for grading the certainty of evidence, one recommendation to guide policymaking which used GRADE-ADOLOPMENT (GRADE Evidence to Decision frameworks for adoption, adaptation, and de novo development of trustworthy recommendations) (n = 1, [47]), documents in which GRADE was used on another development stage of the document (i.e., recommendations where GRADE ratings of included systematic reviews were evaluated, n = 2, [52,53]), or documents in which the barriers against the use of GRADE were stated (n = 3, [30,32,42]) (see Table 4). Table 3 shows the ratings of the certainty of evidence for all PEN-related outcomes for each study (max.…”
