Definition

Data

Description of the data used for obtaining the value of the variable
(e.g. measurement data; mathematical method and its parameters). 
Please include references (preferably using the <ref> </ref> tags) and links to original data, as appropriate.

Dependencies

Unit

Unit in which the result is expressed.

Formula

  • Asthma prevalence is estimated by summing in-patients and day-cases from the hospital morbidity database.
  • Wheeze ERF used, as it approximately corresponds to the type of cases likely to be registered by the database.
