Competing Interests
The authors have the following interest. Prof van Os conducts other studies, not related to the study that is the subject of the authors' submission and approved by the standing ethics committee, that are in part supported by unrestricted grants from Janssen-Cilag, Eli Lilly and Co, AstraZeneca, and Lundbeck. This does not alter the authors' adherence to all the PLOS ONE policies on sharing data and materials.
