“…Of the twenty studies, four of them, or 20%, showed evidence focused only on patients diagnosed with an RD (Adams et al, 2018; Alarcón‐Ovalle et al, 2016; Christensen et al, 2017; Jensen et al, 2019), and 45%, nine studies of the total, reported only on relatives (Anderson et al, 2013; Bendixen & Houtrow, 2017; Cardinali et al, 2019; Custódio et al, 2018; Esteban et al, 2015; Germeni et al, 2018; Granero‐Molina et al, 2020; Lim et al, 2012; Zurynski et al, 2017). Then, four studies focused on both family members and patients with an RD, representing 20% (Behan et al, 2016; Esquivel‐Sada & Nguyen, 2018; Henderson et al, 2009; Requena et al, 2014), whereas only one study focused on RD experts (Blöß et al, 2017). One included patients, relatives and lawyers (Kesselheim et al, 2015), and one included patients, relatives, organisations and healthcare professionals related to RDs which represent 5% each (Lopes et al, 2018).…”
