Table 1. IL-17A, IFN-γ and Foxp3 mRNA levels correlate in small intestinal mucosa of patients with untreated celiac disease (Untreated CD) but not in symptom-free celiac disease patients on gluten-free diet (Treated CD).

	Untreated CD		Treated CD
mRNA species compared:	r	P-value	r	P-value
IL-17A versus IFN-γ1	0.532	0.05 2	0.01	NS3
IL-17A versus Foxp3	0.61	0.02	0.10	NS
IL-17A versus IL-10	0.42	NS	0.20	NS
IL-17A versus TGF-β1	0.12	NS	0.18	NS
Foxp3 versus IFN-γ	0.02	NS	0.38	NS
Foxp3 versus IL-10	0.27	NS	0.17	NS
Foxp3 versus TGF-β1	0.04	NS	0.52	0.02

¹mRNA expression levels were compared in each individual sample.

²r- and P-values obtained by correlation analysis between indicated mRNA species as determined by two-tailed Spearman rank correlation test.

³NS = not significant, P-value >0.05.
