Scatter plots of correlations between pepsinogens. (A) correlation between in situ PGI (IRS scores were divided into four subgroup, i.e. 0, 1–3, 4–7, 8–12) and serum PGI in total study sample; (B) correlation between in situ PGII (IRS scores were divided into four subgroup, i.e. 0, 1–3, 4–7, 8–12) and serum PGII in total study sample; (C) correlation between serum PGI and serum PGII in total study sample; (D) correlation between in situ PGI (IRS score) and in situ PGII (IRS score) in total study sample.
