Following the publication of this article the authors noted that the IPSS risk assignment was incorrectly listed in the second paragraph of the Results section. The correct proportions of patients with intermediate-2-risk or high-risk MF should be 40 and 60%, respectively, not 60 and 40% as listed in the original.

The authors wish to apologize for any inconvenience caused.
