## 3 Results  
The search conducted in the databases mentioned above resulted in 98 articles. After eliminating 45 articles, of which 13 were considered duplicates and 32 did not meet the inclusion criteria, 53 articles were screened, from which the respective titles and abstracts were extracted for analysis. After reading their titles/abstracts, 25 articles were eliminated since they did not fit the study's subject. Then, 28 articles were sought for retrieval and selected for full-text analysis, with 12 being unable to be retrieved, preventing the full reading of the text. Finally, 16 articles were included in the present integrative review. The flow chart representing the research pathway is shown in Figure 1, using the PRISMA flow diagram [24]. The 16 eligible articles were read in full, and their content was analyzed to meet the goals proposed in this integrative literature review. The features and main findings are summarized in Table 1, in descending chronological order of publication. Figure 1: PRISMA flow diagram representing the research pathway. \begin{table}
