Figure 6. Preoperative MAO in patients disease-free after resection of gastrinoma.
Each symbol represents data from one patient. Closed symbols are from patients without previous gastric acid-reducing surgery (n=9) and half symbols are from patients with previous acid-reducing surgery (n=41). Patients were stratified into 3 different groups based on their highest postoperative acid secretory rate as defined in Figure legend 1. The horizontal line represents the mean while the vertical bars on either side represent the SEM for each acid secretory category.
