Data were expressed as median and interquartile range (IQR). Four grades: 0 = none or minimal, 1 = mild, 2 = moderate, and 3 = severe.

The correlation coefficient (r_s) between the mucosal thickness or histological scores and atrophy degrees was calculated by Spearman rank correlation.

CI = confidence interval.
