Distribution of expression of EPOR (relative to CYCA) displayed as box plots. The upper and lower boundaries of each box represent the interquartile range (IQR, the range between 25th and 75th percentiles), and the line in the middle of each box represents the median. Values 1.5 × IQR above the 75th or below the 25th percentile are plotted individually as small circles. The numbers under the data labels indicate the number of samples in each group. (A) Expression data from microarrays. (B-C) Results from Taqman RT-PCR for EPOR in TEL/AML1-positive samples compared with TEL/AML1-negative samples. (B) Displays results for available samples included in panel A. (C) Display of the results for an independent set of patient samples.
