**3. Results**

The data total of two hundred and fifty-nine studies were identified from the databases. After removing eighty-three duplicates, one hundred and seventy-six references remained. The titles and abstracts of these articles were reviewed, resulting in a total of sixty-six eligible records. After the complete reading of these records and application of the previously

defined inclusion criteria, two were excluded because they were in a language different from those the research team spoke. Additionally, nine did not comply with the requirements referring to the population, six did not comply with the selected context, and thirty-seven were excluded due to the concept not being stipulated by the inclusion criteria.

As such, after the identification and screening phases of the review procedure (Figure 1), 12 studies were included in this review.
