The initial draft manuscript was prepared by WC and this was circulated to all authors who provided references and additional content. Editorial assistance and manuscript preparation was then undertaken by a medical writer before a final draft was circulated for further comment of all authors. The raw data concerning referral thresholds for healthcare professionals in primary and secondary care was provided by Novartis Pharmaceuticals, who also paid for the services of the medical writer. The paper was reviewed by Dr Adam Strong of Novartis prior to submission to ensure that it was compliant with ABPI regulations.
