Data!

The authors have made a version of the data for Lancet II available to me. Thanks! To be honest, I had worried that they wouldn't do so. I was wrong to worry. I appreciate the authors sharing this data with me (and others). I also thank them (in advance!) for answering the questions that I and others will have.

A central value of any good scientific community is transparency of methodology. If you want to claim that X is true, you need to explain in detail why X is true and demonstrate how other scientists, especially those who disagree with you, can replicate your results. The Lancet authors have taken the first step along this road. Good for them.
