Figure 2. Highest postoperative BAO after curative resection of the gastrinoma.
Each symbol represents data from one patient. Based on the level of the highest postoperative BAO, patients were stratified into three acid secretory categories defined in Figure 1 legend. Nine patients had previous gastric acid-reducing surgery while 41 patients did not. Data from patients without acid-reducing surgery are shown by the solid symbols and with previous acid-reducing surgery by the half-filled symbols. The horizontal line represents the mean while the vertical bar represents the SEM for each acid secretory category.
