Criteria for including studies
A search was performed on PubMed, Lilacs, Central Cochrane and Scielo electronic databases looking for relevant published literature published until January 2020 based on studies where a decannulation algorithm or protocol was applied to 1 to 18 year-old pediatric patients who suffered tracheostomy. The eligibility criteria were applied independently by two evaluators aiming to include the studies on the revision and the bias risk was independently evaluated by two statisticians using the “STROBE” observational studies guide.
