In a nationwide study of more than 44,000 patients with celiac disease and 412,000 individuals with a normal small intestinal mucosa, researchers at Karolinska Institutet, Sweden, Calgary University in Canada, Columbia University and the Mayo Clinic in the Unites States, examined the incidence of celiac disease over a 25-year-period and the role of celiac disease awareness. The findings have now been published in the journal Gut.
