Table 1

Statistical analysis of the three groups of Slavic subjects studied.

IgA antibodies evaluated with	Examined group	Number of patients	Mean	SD	Dunn’s test
Anti- tTG ELISA (RU/mL)	Group I	24	2.35	1.58	Group I versus group III 𝑃<0.001; Group II versus group III 𝑃<0.001; Group I versus group II 𝑃>0.05
	Group II	25	13.57	46.57
	Group III	31	429.20	435.23
Antigliadin (GAF-3X) ELISA (RU/mL)	Group I	24	1.43	3.32	Group I versus group III 𝑃<0.001; Group II versus group III 𝑃<0.001; Group I versus group II 𝑃>0.05
	Group II	25	15.10	44.17
	Group III	30	271.00	499.25

Explanations: group I: healthy controls, group II: IgA/neutrophil-mediated non-DH dermatoses group, group III: DH patients. SD: standard deviation.
