We identified a total of 1875 records.(1791 in PUBMED, 53 in LILACS and 31 in Scielo). 109 were selected by title and abstract reading including pediatric and adult population,  6 out of the 109 studies were eliminated because of being duplicated in the other bases and 4 because on the basis of being reviews or consensus and were used as theoretical framework and for supporting arguments. 76 out of the 99 resulting articles corresponded with adult population (76.76%) 22 with pediatric population (22.22%) and 1 study about predictors was not aligned with the objective after reading the full text. A total of 22 studies were included for data extraction and analysis. The selection process with the reasons by which studies were excluded is enumerated in the flowchart.(Image 1).
After analyzing the selected studies it was decided to undertake a systematic review of existing studies about decannulation without meta-analysis due to the lack of statistical requirements necessary for its development.
