I get the JAMA table of contents by email each week, and noticed today that they've started including more detail about the corrections. This week's errata, for example:
Incorrect Data and Omission of Trial Site and Personnel in: Effects of Tamoxifen vs Raloxifene on the Risk of Developing Invasive Breast Cancer and Other Disease Outcomes: The NSABP Study of Tamoxifen and Raloxifene (STAR) P-2 Trial JAMA 2007;298 973A small change but seems so much more informative about the nature of the problem, rather than just noting that an error was made and making you go to the full-text to figure out how "big" the error was.
Incorrect Data and Wording in: Patient-Reported Symptoms and Quality of
Life During Treatment With Tamoxifen or Raloxifene for Breast Cancer
Prevention: The NSABP Study of Tamoxifen and Raloxifene (STAR) P-2 Trial
JAMA 2007;298 973
Incorrect Data in Tables in: Nonvalidation of Reported Genetic Risk Factors
for Acute Coronary Syndrome in a Large-Scale Replication Study JAMA 2007;298 973
