Relation between severity of neutrophil inflammation in squamous mucosa and lower oesophageal sphincter/oesophageal body characteristics
| Neutrophil inflammation | ||||
|---|---|---|---|---|
| None (n=28) | Mild (n=12) | Moderate (n=11) | Severe (n=11) | |
| The contraction amplitude refers to the oesophageal contraction amplitudes 6, 11, and 16 cm below the upper oesophageal sphincter. *p<0.01 severe v none; †p<0.05 mild v none and v moderate; ‡p<0.01 severe v none and v moderate; §p<0.01 severe v none and p<0.05 severe v moderate; ¶p<0.01 severe v all other groups. | ||||

| LOS pressure (mm Hg) | 11 (7–18) | 10 (5–18) | 10 (4–25) | 5 (1–10)* |
| Contraction amplitude 6 cm | 34 (22–55) | 21 (20–31)† | 49 (24–71) | 18 (12–28)‡ |
