in my judgement, the quality of this information (methodology, population size, etc.) is not even close to good enough to rely on when making decisions about the well-being of my children. 250 kids, 5 years, study ends when they were 11-15 ... nope, nope, nope.
reminds me of the scene in the most recent yellowstone episode, the scientist stridently insisting destroying 7000 acres of sage brush couldn't possibly hurt sage grouse.
