2G TKI, second‐generation tyrosine kinase inhibition; CI, confidence interval; DMR, deep molecular response; EFS, event‐free survival; MMR, molecular response; OS, overall survival; PFS, progression‐free survival.
EFS‐a: PFS + ELN treatment failure + ELN warning.
EFS‐b: PFS + ELN treatment failure + ELN warning + frontline TKI discontinuation (except treatment free remission).
