Lundell LR et al. Endoscopic assessment of oesophagitis: clinical and functional correlates and further validation of the Los Angeles classification. Gut. PMID: 10403727. Grade A is a break of 5 mm or less that does not extend between fold tops. Grade B is a longer break that still does not bridge fold tops. Grade C bridges fold tops but involves less than 75% of the circumference. Grade D involves at least 75%. (1999)
