Erratum to: 'Perioperative use of crystalloids in patients undergoing open radical cystectomy: balanced Ringer's maleate versus a glucose 5%/potassium-based balanced solution: study protocol for a randomized controlled trial'.

Unfortunately, the original version of this article [1] contained a few errors in Table 1. The correct data for Table 1 has now been included below.
