Fig. 2.
The percentages and absolute numbers of A2-NLV–specific CD8+ T cells in peripheral blood are strongly and positively correlated.
On the x axis, the percentage of A2-NLV–specific CD8+ T cells (expressed as a fraction of total CD8+ cells) is shown; on the y axis, the absolute number of A2-NLV–specific CD8+ T cells (expressed in counts per microliter). Data are from 29 blood samples of 29 healthy HLA-A*0201+, CMV-seropositive SCT donors or laboratory workers (●) and from 71 blood samples obtained from 18 HLA-A*0201+, CMV-seropositive SCT recipients (○). Overall, Spearman rank correlation test is r = 0.94 (P < .0001). Logarithmic scales were used for the x and y axes to compress the figure.
