Naive CD4 T-cell activation identifies MS patients having rapid transition to progressive MS

When the original version of the article “Naive CD4 T-cell activation identifies MS patients having rapid transition to progressive MS” by E. Zastepa et al. (Neurology® 2014;82:681–690) was published online ahead of print on January 22, 2014, there was an error in table 1. In the column “SP-1 (n = 6),” line 2, “Age at MS onset, y (SD)” should have read “30.5 (10.2).” The errors were corrected in version 2, which was posted online ahead of print on February 14, 2014. The authors regret the errors.
