Grades of acute and chronic cardia inflammation according to clinical group, Helicobacter pylori (Hp) status, and bile reflux index (BRI). Grades 1, 2, and 3 are equivalent to a mild, moderate, and marked increase. For acute inflammation grade 0=absence of polymorphs; for chronic inflammation 0=“normal” numbers of lymphocytes and plasma cells (see text)
