Figure 2: The changes of percentage of CD8+ T cells after radical pancreatectomy. A. The percentage of CD8+ T cells for each patient (pre-surgery vs. postsurgery, n=13) B. The percentage of CD8+ T significantly increased after radical pancreatectomy (p=0.00186). Data are expressed as fold change (post-surgery vs. pre-surgery). Statistical significance was determined using the paired t-test.
