Establishment of the KISS for MDS risk stratification. (A) Pearson correlation matrix of the 7 kinases selected into the KISS model, and heat map illustrating the normalized expression of the kinases, across the patients in the NTUH-A cohort. Patients with higher-risk MDS (EB1 and EB2) were notably clustered within the KISS-high subgroup. OS (B) and LFS (C) of patients with MDS in the NTUH-A cohort, stratified by the KISS. (D) OS of patients with MDS in the GSE114922 data set, stratified by the KISS. (E) OS of patients with MDS in the GSE58831 data set, stratified by the KISS.
