Competing Interests

The authors recognise that Novo is a funder of a commercial enterprise but Novo had no involvement in the paper apart from providing some funding for writing. They do not own the data and had no financial links to the study at the time of study design or data collection. They have not seen the data, were not involved in shaping the analysis and have not expressed views on the paper. The authors have read the journal’s policy on conflict of interest and the funding supplied by Novo in no way compromises or influences the scientific integrity of the paper. This does not alter the authors’ adherence to all the PLoS ONE policies on sharing data and materials.
