REGRESSION, DYSPLASIA

Median, interquartile range (IQR), and range were calculated for endoscopy duration at different BE length strata. Mean and range were determined for number of quadrantic biopsies. Comparison of endoscopy duration and number of biopsies at different BE length strata were compared using a one-way analysis of variance.

The effect of BE length on endoscopy duration was determined using linear regression. Endoscopy duration and number of Seattle protocol biopsies per 2 cm of BE length were compared between consultant and independent trainee groups using unpaired Student’s

We aimed to determine the effect of endoscopy duration on dysplasia detection. Both endoscopist experience
All statistical analyses were conducted using SAS 9.4 software (Cary, North Carolina, USA).
