Data Field Description	Paediatric diabetes unit code (These are participating sites within England)	Paediatric diabetes unit Name (These are participating sites within England and Wales)	Total no. of patients with diabetes submitted by Paediatric diabetes unit	Total no. of patients eligible for HbA1c analysis.
