One of the authors is the mother of teenage children with coeliac disease. Another author was diagnosed with coeliac disease at the age of 27 years.

The other author does not have coeliac disease or an immediate family member with coeliac disease. The research team therefore has a productive combination of insiders and outsiders.
Lavis et al. (Wed,) studied this question.
