Compared to normosecretors:
P <0.001,
P <0.03: Compared to moderate hypersecretors:
P <0.05.
Secretory groups are as defined in Table 1 legend.
Increase in serum gastrin level following secretin injection [28].
This is the last gastric acid antisecretory drug used prior to surgery.
Total duration is the total time the patient was treated with any gastric acid antisecretory drug prior to curative resection.
Dose of antisecretory drug patient was taking at the time of curative resection. All histamine H2-inhibitors were converted to ranitidine equivalents as previously described [26,80].
