Fry T. If it‘s worth doing, let‘s do it! Arch Dis Child 2008;93:267–8. The following competing interest statement should have been included with this article.

Under an agreement with the UK Charities Commission, Novo Nordisk UK (who make growth hormone therapies) fund a proportion of Mr Fry‘s salary so that he can run the Child Growth Foundation (CGF) full time — he receives no direct financial support from the CGF. The foundation receives ah hoc fees from a number of drugs companies who buy the auxology training course. In addition CGF manages certain research projects for clinicians that are funded by drug companies (CGF receives no management fee but profits from the bank interest accrued while the research is being conducted).
