Kaplan-Meier plots, stratified by the integration of IPSS-R and lncRNA scores. (A) OS and (B) cumulative incidence of AML transformation of the 164 patients in the training cohort who had cytogenetic data at diagnosis (thus IRSS-R could be calculated). The incorporation of the lncRNA scoring system into the traditional IPSS-R classification could refine risk stratification of MDS patients.
