Stratified variables: Karnofsky performance score. Poor risk cytogenetics significantly associated with risks of relapse in RIC and MAC adjusted for other covariates. Bolded P values are independently significant P < .05.
Adjusted multivariate analysis for the end points shown stratified as indicated.
