Competing Interests

One of the authors (Richard Kravitz) is the Editor of the J Gen Intern Med. This project was his idea. He purposefully (by design) had no involvement in data collection or analysis. He helped with manuscript revision and made several suggestions for additional analyses. None of the authors have any other competing interests. This does not alter the authors' adherence to all the PLoS ONE policies on sharing data and materials.
