Correlation between fasting serum gastrin and secretin, calcium and meal provocative test results in ZES patients. Data from 280 NIH patients and 355 from the literature are shown. The correlation between the fasting serum gastrin level expressed as a fold increase and the absolute change in serum gastrin concentration after secretin injection (upper panels) or calcium infusion (middle panels) as well as the relative change in serum gastrin concentration after a standard meal (lower panels). Each point represents data from one patient. Indicated are the regression line and the correlation coefficient (r) using a least-squares analysis. Literature data are from publications listed in Table 2.
