Prevalence of functional gastrointestinal disorders in children with celiac disease on different types of gluten-free diets

Table 1 Distribution of gastrointestinal symptoms in the celiac disease patients at T0 and T1 in both groups

All disorders	Group	T1 absence	T1 presence	P value
T0 absence	Group A	19	6	< 0.0011
	Group B	20	4	0.0011
T0 presence	Group A	26	4	< 0.0011
	Group B	21	4	0.0011

¹P values were computed with the McNemar test. T0 was the time at the initial diagnosis of celiac disease. T1 was the time at the 1-year follow-up after diagnosis of celiac disease. In group A, patients consumed a gluten-free diet with processed foods. In group B, patients consumed a gluten-free diet with natural foods.
