Is this cohort part of a consortium? (name consortium)
|
|
No
|
Participation in pooled analyses
|
|
- The cohort is potentially interested in participating in pooled analyses of (European) occupational cohort studies (note pooled analyses also includes remote decentralized analyses that would not require any transfer of primary data as well as meta-analyses).
|
Main aim of cohort, please briefly describe the main objectives of the cohort
|
|
The main aim of the cohort is to investigate respiratory health effect of wood dust exposure. A second aim is to identify determinants for wood dust exposure
