Table 5 Comparison of endoscopic corpus atrophy between stages of AIG

From: Evaluation of screening tests for autoimmune gastritis in histopathologically confirmed Japanese patients, and re-evaluation of histopathological classification

Endoscopic corpus atrophy Number of patients
Stage of AIG
Florid stage (N = 4) End stage (N = 18)
O-p 3 17
other than O-p 1 1
O-p ratio 75% 94.4%
  1. Endoscopic corpus atrophy was evaluated with Updated Kimura–Takemoto classification
  2. O-p ratio was compared between florid and end stages; P = 0.22, chi-square test
  3. AIG; autoimmune gastritis
