Event-free Survival Probability by Risk Group at 10-year Follow-Up |
Event-free survival (EFS) is based on the time from protocol enrollment to the occurrence of first event (relapse or progressive disease, subsequent malignancy, or death from any cause). Patients not experiencing an event are censored at their last follow-up date. Event-free Survival Probability will be estimated by Kaplan-Meier (KM) method with a 95% confidence interval calculated using the with Greenwood's formula. |

Correlation of Agreement Between Patient Physical QoL and Parent Proxy Physical QoL at Multiple Time Points. |
Assess and compare the patient reported and parent proxy physical quality of life across multiple time points using the Peds Quality of Life version 4. Assessment was performed across all risk groups. The QL scoring is a 5-point Likert scale from 0 (never) to 4 (almost always). Scores are transformed on a scale from 0 to 100. Items are reverse scored and linearly transformed to a 0-100 scale as follows: 0=100, 1=75, 2=50, 3=25, and 4=0. Total score is the sum of all items over the number of items answered on all scales. The higher the score, the better the quality of life. |
