Probability of survival by Kaplan-Meier estimates.

Survival rates were compared between patients with the T-cell type and NK-cell type of CAEBV infection. The differences between groups were analyzed using a log-rank test. (A) All patients (T-cell type, 16 cases; NK-cell type, 12 cases). Probability of survival at 5 years was 0.55 ± 0.15 for T-cell type and 0.88 ± 0.11 for NK-cell type, respectively. (B) Patients without transplantation (T-cell type, 13 cases; NK-cell type, 9 cases). Probability of survival at 5 years was 0.41 ± 0.18 for T-cell type and 0.83 ± 0.15 for NK-cell type, respectively.
