manipulate your data, says paul campos.

The researchers collected data from 527,265 AARP members, who were followed for 10 years. What they found was exactly the same result reported by Flegal and her colleagues: Among both men and women, "overweight" people had the lowest mortality risk. This result, however, was clearly unacceptable. So they began torturing their data.

campos doesn't mention the title nor the researchers in question, but i did a quick search and the study he's referring to must be Overweight, Obesity, and Mortality in a Large Prospective Cohort of Persons 50 to 71 Years Old, by Kenneth F. Adams, Ph.D., Arthur Schatzkin, M.D., Tamara B. Harris, M.D., Victor Kipnis, Ph.D., Traci Mouw, M.P.H., Rachel Ballard-Barbash, M.D., Albert Hollenbeck, Ph.D., and Michael F. Leitzmann, M.D. now to get my hands on the full text.

i notice that in the same issue (what is this, fat week at NEJM? there are 5 items dealing with weight issues) is an article from a baby boomer concerned with his weight that makes reference to this study. anyone here have a subscription to NEJM who can tell me whether that guy noticed the problems with the study?
