RT Journal A1 Zollinger, Paul E. A1 Breederveld, Roelf S. A1 Tuinebreijer, Wim E. A1 Kreis, Robert W. T1 Can Vitamin C Prevent Complex Regional Pain Syndrome in Patients with Wrist Fractures? JF The Journal of Bone & Joint Surgery JO The Journal of Bone & Joint Surgery YR 2008 FD February 1 VO 90 IS 2 SP 448 OP 448 DO UL http://dx.doi.org/ AB Mr. Rogers and Mr. Ricketts are right that rats were used in the study by Kearns et al.1. However, the steady-state level of vitamin C in humans is mentioned in the discussion of their article. We wanted to combine the article by Kearns et al.1 with their citation of the earlier results reported by Levine et al.2, but it would have been better to mention them separately. Furthermore, we did not give the credit to Levine et al. that they deserve. We apologize for this.
