Funding

The initial laboratory investigations and field studies were supported financially by Charwell Pharmaceuticals Ltd, Alton, UK, as part of a new product development programme prior to their acquisition by Pfizer Inc., and inclusion in Unicliffe Limited. Employees of Charwell Pharmaceuticals Ltd filed patents based on the work in support of a commercial product launch, but that intellectual property has now lapsed. The company did contribute ideas towards the design of the studies and conducted their own analyses of the results, which were not disclosed to the investigators. David Merrington contracted the work and William (Bill) Oliver and Richard Irwin provided technical and logistical support and study supplies. Monitoring of documentation from both field studies was performed by an appointee of Pfizer Inc. on behalf of Charwell Pharmaceuticals Ltd. Only as far as is stated in the Funding Statement
