Prevalence of neutrophil and mononuclear cell infiltration in columnar mucosa obtained from biopsy specimens of the gastro-oesophageal junction in 126 patients with a normally positioned Z-line. For each type of columnar mucosa prevalence of inflammatory cell infiltration is presented according to the presence or absence of Helicobacter pylori infection. Note the high prevalence of acute and chronic inflammation in cardiac type mucosa which was unrelated to H pylori. *p<0.05 v fundic H pylori negative, **p<0.01 v cardiac H pylori negative or fundic H pylori negative, †p<0.01 v fundic H pylori negative.
