Dr David Spence, Clinical Director and Consultant Physician at Bristol Homeopathic Hospital and Chairman of the British Homeopathic Association, a co-author of the study, said "These results clearly demonstrate the value of homeopathy in the NHS". The study, which asked people how happy they were after having some homeopathy, appears to have had no control group, no randomisation and blinding, no control of whether patients were receiving other (conventional) treatments, and the outcome measure was not calibrated or universally recognised. Many critical comments about the study are contained in this link. Ben Goldacre, MD, Bad Science (21st November 2005)
