I did a thorough re-analysis of the data in this paper, and it shed serious doubt on the validity of the findings. My re-analysis was briefly summarized in NEJM at http://www.nejm.org/doi/full/10.1056/NEJM200504073521422 and in much more detail in http://www-stat.stanford.edu/~tibs/FL/report

I use this example as a teaching tool, demonstrating how the lack of reproducibility of findings is a serious problem, especially in the age of "big data".
