Correction to: Association of plasma potassium with mortality and end-stage kidney disease in patients with chronic kidney disease under nephrologist care - The NephroTest study.

In the original version of this article [1], published on 12 September 2017, the explanation of a and b in the footnote of Table 2 were switched during typesetting. In this Correction Table 2, the incorrect and correct version of its footnote are shown. The affected part of the footnote is marked in italics. The original publication of this article has been corrected.
