CRIM, cross-reactive immunological material
aModels are adjusted for age (as time scale), age at first treatment, sex, and CRIM/ITI group
bp-value for interaction between the stratification variable and average dose over time, i.e., is the association between average dose and survival significantly different for the two subgroups. Calculated from likelihood ratio test comparing the main (non-stratified) model to the main model with an interaction term
cAverage dose received over time from first treatment, updated over time, measured in multiples of the label dose. Range: > 0 to 4 times label dose
