In the article entitled “Protection or Nonprotection in Carotid Stent Angioplasty: The Influence of Interventional Techniques on Outcome Data From the SPACE Trial” by Jansen et al,1 the authors would like to note an error in the Abstract, 2nd and 3rd lines under Results. The sentence “The outcome event (OE) of the analysis … in the protection group and in 12/145 … patients in the nonprotection group (P=0.40).” should read “The outcome event (OE) of the analysis … in the nonprotection group and in 12/145 … patients in the protection group (P=0.40).” In other words, “protection group” and “nonprotection group” should be transposed. The authors regret this error.
