Figure 2: PG I and PGR in superficial gastritis group and atrophic gastritis group compared with gastric cancer.
From: The Serum Pepsinogen Test as a Predictor of Kazakh Gastric Cancer

(A) PGR in atrophic gastritis group and superficial gastritis group were significantly higher than that of the gastric cancer group. B) Serum PG I concentration in superficial gastritis group was significantly lower than that of gastric cancer. (**P < 0.01, ***P < 0.001).
