Figure 1 Submaximal acid output before, during, and at various time periods after stopping omeprazole in the 3 groups studied. Values are shown as percentage of pretreatment value (column 0), which is expressed as 100%. Column 1 is during treatment and colums 2, 3, 4, 5, and 6 represent days 7, 14, 28, 42, and 56, respectively, after stopping treatment. The horizontal bars indicate median values.
