Values shown are means plus or minus standard deviations.

P values for the comparison of paired data (before and after) using paired t test.

P values describe the comparison of before-imatinib treatment data with before-α-interferon treatment data using the t test.

P values describe the comparison of after-imatinib treatment data with after-α-interferon treatment data using the t test.
