↵2-150 Mean score of three sites.
↵2-151 Mean of two sites along the greater curve.
↵2-153 Only grade 4 indicates atrophy; grades 1–3 represent mild, moderate, or severe grades of superficial gastritis. The score represents the maximum severity of involvement in any portion of the antrum, and thus a worst case scenario. The intestinal metaplasia score, in turn, reflects the horizontal extent of the biopsy occupied by the metaplasia (see methods section).
