Erratum to: ‘Early versus late initiation of renal replacement therapy in critically ill patients with acute kidney injury (The ELAIN-Trial): study protocol for a randomized controlled trial’

Unfortunately, the original version of this article [1] contained an error. There is a typo in one of the formulas in the PDF version of this article on page six, though the HTML version has the correct formula. To avoid confusion the correct formula has been included here.

$$C\left(p1,p2\right):=1-\varphi \left[\sqrt{\frac{1}{2}}\cdot {\varphi }^{-1}\left(1-p1\right)+\sqrt{\frac{1}{2}\cdot }{\varphi }^{-1}\left(1-p2\right)\right]\le {\alpha }_c$$
