“…Although the participants in all studies had a clinical diagnosis made at first contact, in only 8 studies were further investigations done to confirm the clinical diagnosis [30–32, 34–37, 39]. Seven of the 11 studies reviewed reported the percentage of participants with atopy, with the figure ranging from 7.1% to 92.4% of the study participants [30, 31, 34, 35, 37–39]. Five studies used the SF-36 or part thereof [29, 33, 37–39], seven used the DLQI [29, 30, 32, 33, 35, 36, 39], and three used the Skindex questionnaire [31, 37, 38].…”
