  • This table compares all groups to the non-dysplastic cohort using both mean scores, after propensity score matching, and the categorical breakdown (normal, borderline and positive). P values are derived by Fisher’s exact test.

  • *p values <0.05 were deemed statistically significant.

  • DBO, dysplastic Barrett’s oesophagus; GORD, gastro-oesophageal reflux disease; HADS, Hospital Anxiety and Depression Score; NDBO, non-dysplastic Barrett’s oesophagus.
