How Effective Was Gleevec Against Cancer? (Continued)

The colored lines show the white blood cell counts of six different patients with CML. They all show a decrease in response to Gleevec. These results suggested the treatment was working.

A line graph with 6 different colored lines representing 6 patients. X axis is labeled Days on Gleevec with values ranging from 0 to 150 in increments of 30 days. Y axis is labeled White Blood cell times 10 to the third microliters with values ranging from 1 to 100. A horizontal band labeled normal range highlights 5 to 10 from the Y-axis and extends the width of the graph. All patient data starts above normal range, between 10 and 100, at zero days, then drops to normal or below normal range by 30 days, and then plateaus.
