Errata reporting

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;298 973

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
http://jama.ama-assn.org/cgi/content/full/298/9/973-b?etoc

A 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.
