Cumulative survival in cases with dyskeratosis congenita after bone marrow transplantation, calculated using the method of Kaplan and Meier. (A) Cases reported in the literature through 2008, N = 65. (B) Cases enrolled in the NCI IBMFS DC cohort through 2007, N = 11. Data are the cumulative number of patients surviving, censored for last known age alive.
