“…Most of the studies (26/30, 87%) had an observational or cross-sectional design ( Table 1 ), 3% (1/30) were randomized controlled trials [ 6 ], 3% (1/30) used another experimental design [ 28 ], and 7% (2/30) used qualitative approaches [ 23 , 25 ]. Reported limitations were the small number of participants [ 8 , 12 , 26 , 27 , 34 ], pilot studies [ 22 ], a single type of health professional included [ 6 , 8 , 9 , 25 , 29 ], years of clinical practice for specialists [ 9 ], poor response rate [ 26 , 27 , 33 , 34 ], possibility of socially desirable answers [ 29 , 35 ], and a single study setting [ 21 , 22 , 25 , 29 ]. The limitations of the studies performed on data or journals were the small number of journals [ 7 , 36 ], small number of analyzed journal issues [ 2 ], filters for web-based image search, and the fluctuating number of available web-based images from academic journals [ 3 ].…”
