Referee comments: Referee 2 (Paul Ciclitira)

Referee 2's review (Paul Ciclitira):

My only suggestion is in the introduction the prevalence of celiac disease is 3:100 in Sweden, 2:100 in Ireland and 7:100 in the Sahara (Catassi et al). They might therefore consider increasing their prevalence from 1:100 slightly.
