Figure 2 Fasting (A) and postprandial (B) serum G-17 levels in patients with or without long-segment BE among patients and controls with normal and healthy stomach mucosae (no gastritis, no H. pylori, and no atrophy). A box plot presentation (see Figure 1). Differences: a: P<0.001; b: P=0.528; non-parametric test (MannWhitney U). To make the figure clear, the very most extreme outliers are not shown in the pictures.
