Notes:

Total study population: 1,964,337 (over 14 years of age).

Dx: Diagnoses refers to individuals who have visited their general practitioner or have been admitted to hospital and have been diagnosed at least once with one of the listed medical conditions during the 12 months of the study.

Rx: Prescriptions means that in the primary care electronic medical record there is an entry corresponding to the issuing of a prescription (during the same 12-month period) from which it is deduced that the patient has one of the listed medical conditions.

These three sources of information are not exclusive – a single patient may be detected as having one these medical conditions through hospital, primary care and prescriptions data, although only is counted once.

The health survey covered all the population, including children.
