Figure 2: Analysis of age at diagnosis and survival. Kaplan-Meier survival curves of patients diagnosed with extrarenal extra-CNS malignant rhabdoid tumor. Age classes under 2 years old were indistinguishable. Age class 2–10 years had the best prognosis and were significantly different than those age classes under 2, but were not different from the >10-year-old age group. The >10 age group was significantly different from the <2-year-old group.
