Three-scaled histomorphologic scoring algorithm developed by us indicating the severity of the lesions according to microscopic findings of NSAID-related acute erosive/hemorrhagic gastritis

Score	Microscopic findings
1	Superficial epithelium is intact, edema at superficial lamina propria, dilated and congested capillary structures, extravasated erythrocyte and tiny fibrin clots
2	Multiple focal scattered erosions + 1
3	Disappearance of superficial epithelium, presence of proteinose materials on the surface of epithelium, diffuse hemorrhages within lamina propria, transmural ischemic necrosis + 2
