Fig. 2

Total number of naïve T cells and CD31 positive and negative CD4⁺ naïve T cells in relation to age. Total naïve CD4⁺, CD31 positive (CD31⁺) and CD31 negative (CD31⁻) naive CD4⁺ T cells and total naïve CD8⁺ T cells are shown for renal transplant recipients (n = 211) and healthy controls (n = 239). The cross-sectional data are represented in means with standard error of the mean for healthy controls (black dots), recipients alive (green dots) and deceased recipients at the time of follow-up (red dots). Age is shown in decades on the X-axis. Dashed interconnecting lines are added to facilitate interpretation of the graph
