In the article “Ablation of Cellular Prion Protein Does Not Ameliorate Abnormal Neural Network Activity or Cognitive Dysfunction in the J20 Line of Human Amyloid Precursor Protein Transgenic Mice,” by Moustapha Cissé, Pascal E. Sanchez, Daniel H. Kim, Kaitlyn Ho, Gui-Qiu Yu, and Lennart Mucke, which appeared on pages 10427–10431 of the July 20, 2011 issue, the authors have issued a correction to the legend of Figure 3, as listed below. This error (and its correction) does not affect the scientific integrity of the data in particular or that of the paper in general.
The original legend was as follows:
C, Kaplan–Meier survival plot shows more mice with hAPP died prematurely than mice without hAPP after weaning (p < 0.01, Mantel–Cox test). Premature mortality was greater in hAPP/Prnp−/− mice than in hAPP/Prnp+/+ mice (p < 0.001, Mantel–Cox test).
The corrected version is as follows:
C, Kaplan–Meier survival plot shows more mice with hAPP died prematurely than mice without hAPP after weaning (p < 0.05, Wilcoxon test for equality). Premature mortality was greater in hAPP/Prnp−/− mice than in hAPP/Prnp+/+ mice (p < 0.05, Wilcoxon test for equality).
