Performance of AGE + ELN₂₀₁₇ Model in Viable Leukemic Blasts. Overall Survival probability over time as predicted by the AGE + ELN₂₀₁₇ models developed using the discovery cohort in MNCs. The continuous risk score from the AGE + ELN₂₀₁₇ model in the discovery cohort was divided into quartiles and the boundaries of these quartiles were used to defined a four-level categorical variable. A model was fit using this categorical variable in the validation cohort for all patients (N = 166, age 18.5–88.8, a), patients younger than 55 years old (N = 86, b), and patients 55 years and older (N = 80, c). There were no patients younger than 55 in 4th quartiles (b) or patients older than 55 in 1st quartile (c). The total number of patients who were at risk of death (alive and uncensored) are shown for each year of follow-up
