Correlation between the maximal acid output (MAO) and the ability to withdraw antisecretory therapy successfully after curative gastrinoma resection^*

	Number of patients
MAO (mmol/h)	Withdrawn	Not withdrawn	Total
Normal†	11	4	15
Elevated	5	7	12
Total	16	11	27‡

^*Values indicate the number of patients in whom antisecretory medication was or was not successfully withdrawn in relation to the maximal acid output at the time of attempted drug withdrawal.

^†Normal MA0 is < 48 mmol/h for men and < 30 mmol/h for women (see reference 28).

^‡One patient excluded (see Table 3).

There is no significant difference between the proportion of patients with normal or elevated MAO who were successfully withdrawn from antisecretory therapy (P = 0.08, Fisher’s exact test).
