^AThe Omnibus test was performed using the two-tailed Fisher-Freeman-Halton 3 × 2 probability test.

^BBE, Barrett’s esophagus.

^CThe follow-up tests were performed with the two-tailed Fisher exact 2 × 2 probability test.

Tests that are statistically different at the false discovery rate < 5% ²¹ are marked by *.
