Table 3. Proportion of ESMGs with Inflammation Grades 0–3 for Cases (N=147 ESMGs) and Controls (N=195 ESMGs) and non-EAC (N=695 ESMGs).

The proportion of ESMGs with each category of inflammation Grades 0–3 as scored (where 0=none, 1=mild, 2=moderate, 3=marked) was calculated for both cases (EAC and non-EAC) and controls. Chi-squared or Fisher’s Exact Tests, as appropriate, were used to compare the proportions between Non-EAC cases, EAC cases, and controls.

Grade	HGD/EAC Cases	Controls	Non-EAC Esophagectomy	P-Values
0	33 (22.5%)	59 (30.3%)	434 (62.5%)	<0.001
1	84 (57.1%)	125 (64.1%)	206 (29.6%)	<0.001
2	21 (14.3%)	10 (5.1%)	46 (6.6%)	0.002
3	9 (6.1%)	1 (0.5%)	9 (1.3%)	<0.001
