Data were expressed 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 female and male patients. was considered statistically significant.
