Publisher Correction: Indole 3-acetic acid, indoxyl sulfate and paracresyl-sulfate do not influence anemia parameters in hemodialysis patients.

Erratum

In the original publication of this article [1], Table 3 is incorrect, several cell values in column 4 (no ESA (n = 8)) have been incorrectly shifted during typesetting.

In this Erratum the correct and incorrect version of Table 3 are published.

The publisher apologizes for the inconvenience caused by this error to the authors and readers.
