Livin expression level with respect to risk factors. (A) The Livin expression level in low-risk patients was higher than in high-risk patients. (B) Similarly, the Livin expression level in patients with t(12;21) was higher than in patients without t(12;21). The Livin expression levels are presented in box plots showing the median and 90th percentiles of Livin expression. Maximum and minimum values are represented by bars. Statistical analysis was performed using the Mann-Whitney U test.
