Survival with restriction to CPX-351 trial-eligible patients and across sensitivity analyses. (A) OS with population restricted to 60 to 75 year olds with a history of a therapy-related myeloid neoplasm, myelodysplasia-related cytogenetics, or history of MDS (n = 267). (B) Plot of HR for OS for CPX-351 vs ven/aza across multiple analyses including unadjusted univariate Cox analysis, multivariate Cox analysis, univariate Cox analysis after multiple imputation, multivariate Cox regression analysis after multiple imputation, and Cox regression analysis after multiple imputation with inverse probability of treatment weighting.
