BE, Barrett's esophagus; CI, confidence interval; GERD, gastroesophageal reflux disease; OR, odds ratio.

Estimates were calculated from logistic regression models.

All models include (control for) age and white race.

Non-Hispanic whites.

Any gastritis is defined by the presence of at least grade 2 neutrophils or mononuclear cells in at least one gastric biopsy site or grade 1 neutrophils or mononuclear cells in at least two sites.
