Magnifying endoscopic (ME) classifications following crystal violet staining and pathognomonic histological features of ulcerative colitis.

Magnifying endoscopic (ME) classification	Severe mucosal inflammation		Crypt abscess		Goblet cell depletion		Total case
	Present	Absent	Present	Absent	Present	Absent
ME-A	0	5	0	5	0	5	5
ME-B	8	14	8	14	12	10	22

ME-A: regular arrangement of normal-appearing round to oval pits; ME-B: irregular arrangement with/without enlarged spaces between the even pits; ME-C: irregular pits in size and shape with more irregular arrangement of pits compared to ME-B; and ME-D: disrupted or disappeared pits.
