The Cochrane Collaboration has adopted The Grades of Assessment, Development and Evaluation (GRADE) System for evaluating the quality of evidence within the context of systematic reviews.
Critical appraisal used the Cochrane risk of bias assessment and Grading of Recommendations, Assessment, Development and Evaluation tools.
A two-tailed, independent t-test was performed for grading of clinical assessments, with P values noted.
We reviewed the available literature and evaluated the quality of included studies according to the Child Health Epidemiology Reference Group CHERGG) adaptation of Grading of Recommendations, Assessments, Development and Education (GRADE) criteria [ 10].
We assessed risk of bias of individual studies and certainty in evidence assessment by the Grading of Recommendations Assessment, Development, and Evaluation approach.
We assessed GRADE (Grading of Recommendations Assessment, Development and Evaluation) and planned to create a 'Summary of findings' table.No studies were eligible for inclusion in this review.
The quality of evidence will be assessed using Grading of Recommendations Assessment, Development, and Evaluation (GRADE) guidelines.
Systematic reviews with meta-analysis of all identifiable randomised clinical trials with Grading of Recommendations Assessment, Development and Evaluation (GRADE) assessment represent the highest level of evidence.
Quality assessment will include using Grading of Recommendations Assessment, Development and Evaluation (GRADE) criteria.
In addition, we conducted a GRADE (Grading of Recommendations Assessment, Development and Evaluation) evidence assessment and profile for each selected outcome.
Overall assessments were made using the Grading of Recommendations Assessment, Development and Evaluation procedure.
