Table 2

Multivariate logistic regression model for the prediction of celiac disease.

Predictor	Coefficient ()	Odds ratio	95% confidence interval
			Lower bound	Upper bound
Based on positive pathology (Marsh I-III)
IDA	0.763	2.14	1.062	4.334	0.03
Anti-TTG	1.270	3.56	1.707	7.432	<0.01
H. pylori infection	1.425	4.16	2.224	7.780	<0.01
Based on both positive serology and pathology
IDA	2.871	17.65	1.538	202.523	0.02

IDA: iron deficiency anemia; TTG: tissue transglutaminase; H: Helicobacter.
