Table 1: Analytic data of the four serological markers in relation to histological diagnosis.


Histological diagnosis	Number of patients	Age (years) (mean ± SD)	PCA (U/mL) (mean ± SD) (cutoff 30)	IFA (U/mL) (mean ± SD) (cutoff 20)	Gastrin (pg/mL) (mean ± SD) (cutoff 115)	Anti-Hp positivity (%)

Group 1: autoimmune gastritis	30					26.0
Group 2: gastric atrophy	14	*		*	*	0*
Group 3: non-specific lymphocytic gastritis	18				*	21.1
Group 4: multifocal atrophic gastritis	21	*	*		*	100*

PCA: anti-parietal-cell antibodies; IFA: anti-intrinsic-factor antibodies; anti-Hp: anti-Helicobacter pylori antibodies; *statistical significance ().
