The information requested has been placed in the Library. However, it should be noted that to protect patient confidentiality it is not possible to provide primary care trust (PCT) level data for the age groups under 10, 10 to 13 and 14 to 17-years-old. Therefore, data have been provided for under 18 years old and over 18 years old, additionally for some PCTs it has been necessary to combine these two age groups to protect patient confidentiality.
