Contents
Scope
This includes a verbal definition of the spatial, temporal, and other limits (system boundaries) of the variable. The scope is defined according to the use purpose of the assessment(s) that the variable belongs to.
Exposure-response function for short-term (acute) exposure to ambient air particulate matter (PM) with an aerodynamic diameter < 10 µm and lower respiratory symptoms (LRS). Lower respiratory symptoms include wheezing, chest tightness, shortness of breath, and cough.
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.
- Annual change of 1.30 (95% Cl 0.15, 2.43) in symptom days per adult with chronic respiratory symptoms per 10 µg/m3 PM10
- Approximately 30% of adult population are estimated to have chronic respiratory symptoms
- Annual change of 1.86 (95% Cl 0.92, 2.77) in symptom days per child (general population) aged 5-14 per 10 µg/m3 PM10
Causality
List of upstream variables. The variables can be listed used descriptive (free-format) names or unambiguous identifiers (e.g. Analytica IDs).
Unit
Unit in which the result is expressed.
Annual change in symptom days per person per 10 µg/m3 exposure
Formula
Algebra or other explicit methods if possible (e.g. Analytica code between the ''<anacode></anacode>'' delimiters).
Result
If possible, a numerical expression or distribution.
