PAB IgG	27.5 (22.0-34.0)	42.0 (27.0-56.0)	<0.0001
PAB IgA	26.0 (20.0-33.0)	40.0 (26.0-55.3)	<0.0001
ANCA IgG	45.0 (31.0-57.0)	39.0 (25.0-54.0)	0.0019

Data were presented as median (IQR) and calculated by Mann–Whitney test. IQR: interquartile range; ASCA: anti-Saccharomyces cerevisiae antibodies; GAB: anti-intestinal goblet cell antibodies; PAB: antibodies to exocrine pancreas; ANCA: anti-neutrophil cytoplasmic antibodies; IBD: inflammatory bowel disease. values indicate differences between antibody positive and negative patients. was considered statistically significant.
