“…The leaflets must be clear and concise in their explanations and must be available in the user's language and adapted to their understanding (Clausen et al, 2016;Khodambashi et al, 2017). However, a considerable proportion of the leaflets evaluated in these articles did not meet these characteristics as they were not understood by the general public (Rajasundaram et al, 2006;Symonds et al, 2011;Brooke et al, 2013;Spinillo, 2014;Bennin and Rother, 2015;Alaqeel and al Obaidi, 2017;Haller et al, 2019), nor did they meet the parameters of utility (Sukkari et al, 2012), readability (Kasesnik and Kline, 2011), adaptation to the educational level of the target population (Cronin et al, 2011), or use of non-medical terminology (Hirsh et al, 2009;Bennin and Rother, 2015). Participants in other studies confirmed that the leaflets were clear, legible (Gustafsson et al, 2005;Williamson and Martin, 2010;Potter et al, 2014), and useful (Edwards et al, 2013), even though the participants showed low scores in a test on knowledge acquired from the PILs (Alaqeel and al Obaidi, 2017).…”
