  • Scientific Objectives
  • 1. Determine the prevalence of COPD and asthma in
    a selected group (possibly to be corrected by
    taking a random sample of the general
    population).
  • 2. Examine whether PEFR is a valid method for the
    detection of COPD.

  • 3. Examine to what extent MEFR and FEF75-25 are
    reduced in patients with COPD and linked to COPD
    more than to smoking.
