In the article, "Critical Appraisal of the Evidence: Part II," published in September in our Evidence-Based Practice, Step by Step, series, it was stated that statistically significant findings are those that have a probability (P) value of less than 0.5. In fact, statistical significance is typically indicated by a P value of less than 0.05.
We regret the error. This error has been noted in the online version of the article, which is available at www.ajnonline.com.
