Correction to: Blood Cancer Journal (2013) 3, e123; doi: 10.1038/bcj.2013.23; published online 12 July 2013
Since the publication of this article, it has come to the authors attention that there are two small syntax errors in the mathematical equations (on page 2) and also within the supplementary table.
While this has no effect on the results, rectifying it keeps consistency between the text and the equation.
In addition, on page 6, the legend to Figure 5 contains an error, in which the citations for panels a and c are incorrectly transposed.
Finally, also on page 6 (third line down), the citation for Figure 5c has been incorrectly written as Figure 4c.
The errors have now been rectified, and the correct article appears online (including the correct supplementary information).
