Competing Interests

I have read the journal's policy and the authors of this manuscript have the following competing interests: Dr. Winkelman is a consultant for Merck and Flex Pharma. He has provided expert testimony for Cantor Colburn. He receives royalties from UpToDate. He has received research grants from Luitpold Pharmaceuticals, Xenoport, UCB Pharma, NeuroMetrix, and NIMH. Dr. Grandner is a consultant for FitBit and is on the Scientific Advisory Board for CurAegis Technologies. He has provided expert testimony for Morrison Foerster. This does not alter our adherence to PLOS ONE policies on sharing data and materials.
