However, the authors do not believe that this would have changed the outcome of the study. Conclusions Nine paediatric doctors, 12 paediatric nurses, 13 paediatric allied health professionals and eight children were recruited to the study within one hour. Exclusion criteria were anyone who had bought a caterpillar cake in the past month; anyone who had any conflict of interest related to specific affection to any particular caterpillar cake; and anyone who had any dietary allergies. Consent was obtained from the adult participants, and parental consent for the children involved in the study.
