All the microarray data used in our study were derived from the Gene Expression Omnibus (GEO) and were available for public downloading. Expression data for the 157 CN-AML patients in the primary cohort were detected using an Affymetrix HG-U133Plus 2.0 array [45 (link)], while the validating cohort of 162 CN-AML patients was evaluated using an Affymetrix HG-U133A array [49 (link)]. High-throughput sequencing data from The Cancer Genome Atlas (TCGA) were also used [50 (link)], including mRNA, microRNA and methylation data.
