<<Disclaimer: Verify this information before applying it to your situation.>> Hi, folks, Stats is my business and career. If you need to know what the stats mean in a particluar article or series of, I can try to help. I am also working in medical studies. Although not a DR I have a lot of contacts in that field. Please contact me if you read an article and don't know what to make of it. Hopefully, I can help. Our resident Dr's on the list are our best experts but I have 10 years experiences in picking out what is meaningful in any kind of study in terms of how it was conducted. What I do not have is practical experience and training such as our list DR's have. Lissy (VCR not Oregon, hi Melissa!)
