Data are means ± SD (“Age” and “Percent blasts in samples enriched for blasts”) or case number (“Sex” and “IPSS”).
International Prognostic Scoring System for MDS (Low/INT-1/INT-2/High). Chromosome analysis of some MDS cases did not yield sufficient metaphases, and such cases could not be classified by the IPSS.
Percent blasts in samples that were enriched for blasts by BR density centrifugation and used for the subsequent analyses.
