Figure 2. Five-Year Relative Survival Rate of Patients With Acute Lymphoblastic Leukemia by Single Year of Age at Diagnosis, 2000 to 2007, From the Surveillance, Epidemiology, and End Results 18 Data3.

Figure 2.

A, Included is joinpoint analysis4 that created linear regressions for ages 1 to 17 years and 20 to 68 years and associated statistical variables. B, The pediatric age-dependent survival trend in A is extrapolated into the adult age range. The solid lines are the regressions created by joinpoint analysis, and the vertical solid lines indicate the ages at which the joinpoints were identified. The diagonal dashed line in B is an extension of the survival regression of children.
