Competing Interests

I have read the journal's policy and have the following conflicts: SLG has received a research grant, honoraria, and travel reimbursements from Novartis, and has consulted for Eli Lilly, Pfizer, Amgen, and Novartis. There are no other conflicts of interest. This does not alter our adherence to all PLOS policies on sharing data and materials.
