Error in formula for serum sodium correction. The article “Diabetic Ketoacidosis: Evaluation and Treatment” (March 1, 2013, p. 337) contained an error in Table 4 (p. 340). The formula for serum sodium correction should be Na + 0.016(glucose – 100), rather than Na + 1.6(glucose – 100). The online version of this article has been corrected.
