Table 4 Comparison of serum PGs between stages of AIG

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

Serum PGs Mean ± SD
Stage of AIG
P value
Florid stage (N = 4) End stage (N = 16)
PG I (ng/mL) 22.7 ± 24.5 11.0 ± 17.3 0.31
PG II (ng/mL) 11.9 ± 4.1 10.6 ± 9.1 0.80
PG I/II ratio 1.5 ± 1.2 0.9 ± 0.5 0.39
  1. Serum PGs were compared between florid and end stages; t-test
  2. PG, pepsinogen; SD, standard deviation; AIG, autoimmune gastritis
