  2. The median expression level of miR-425 was used to define high- and low-miR-425-expression groups. P values for continuous variables are from Mann–Whitney test; P values for categorical variables are from Chi square tests. The values represent frequencies (%). Complex karyotype is defined as more than or equal to 3 chromosomal abnormalities. The patients were divided into three risk groups (good, intermediate and poor) according to the cytogenetic risk classification
