counts
Figure 1: Longitudinal analysis of CD4+ and CD8+ T-cell counts for patients with or without EBV reactivation. Patients are subdivided based on their peak EBV load. A) The median number of CD4+ and CD8+ T cells/μl blood is plotted weekly during the first 12 weeks and monthly thereafter until 6 months post SCT for patients without (closed circles) or with (closed triangles) EBV reactivation. B) The median number of CD4+ (left panel) and CD8+ (right panel) T cells during the first 12 weeks after SCT are plotted for patients with (Yes) or without (No) EBV reactivation. In the ‘Yes’ category, open symbols indicate patients with high-level EBV reactivation (>1000 copies/ml) and closed symbols patients with low-level EBV-reactivation.
