Boxes with dashed borders contain brief guidance text for completing the entries for new variables.
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 medication (bronchodilator) usage by people with asthma.
Dimensions and boundaries relevant for the variable
- Age of exposed population
- Country/other geographic area
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.
WHO task group (2004) [1]
- RR of 1.005 (95% Cl 0.981, 1.029) for bronchodilator usage by people with asthma per 10 µg/m3 PM10
- Note! the association is not statistically significant at the usual 5% level.
CAFE CBA (2005)[2]
- change of 180 (95% Cl -690, 1060) days in brochodilator usage per 10 µg/m3 PM10 in children aged 5-14 years
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.
Change in no. of days of bronchodilator usage per 10 µg/m3 increase in 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.
| Age group | Days | 95% Cl |
