Relative and absolute CTLe kinetics. A) Linear representation over time of the CD8/CD4 ratio in the 75 patients with relative CTLe. B) Trend linear plot of 25 patients with a relative CTLe and a follow up of, at least, 1440 days from transplantation. Each line depicts a patientxs longitudinally measured CD8/CD4 ratio. Patients are grouped by similar pattern of ratio behaviour through follow up. The line "slope" depicts the magnitude of the change between time points. C) Linear representation over time of the CD3/CD8 count in PB in the 14 patients with an absolute CTLe. D) Trend linear plot illustrating the CD8/CD4 ratio behaviour of the 14 patients with an absolute CTLe.
