“…After removal of duplicates, i.e., articles that appeared more than once during the literature search because of the utilization of more than one search term, 361 articles remained, which were screened: of these, 333 were excluded because their titles or abstracts were unrelated to the subject. Three more were excluded due to their not meeting the eligibility criteria ( Table 2 ) [ 60 , 61 , 62 ], with, finally, 25 articles remaining for the qualitative analysis ( Table 3 ) [ 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 , 45 , 46 , 47 , 48 , 49 , 50 , 51 , 52 , 53 , 54 , 55 , 56 , 57 , 58 ]. Figure 2 presents the process that followed (PRISMA flow diagram).…”
