Finding F-0089

“Analysis indicated a correlation between ambient PM2.5 levels and decreased PEF over 0-to-3-day lag, with autumn indoor exposure significantly impacting PEF and wheezing.”

Structure

Factor: Particulate matter (PM₂.₅ and PM₁₀)
Outcome: Lung function
Population: five patients with asthma or chronic obstructive pulmonary disease (average age 50 years, 40 % male)
Setting: city (ambient), GR (one year)
Study design: panel study: five patients with asthma or COPD monitored over a whole year with 24 h indoor and outdoor PM2.5 measurements, daily peak expiratory flow and biweekly symptom reports (linear mixed effect models, generalized estimating equations) (class 3)
Averaging time: lag 0 to 3 days
Sample: 5 participants
Caveat: no effect size in the sentence; the same sentence reports autumn indoor exposure significantly affecting peak expiratory flow and wheezing

A Finding records what one published document states, verbatim and with its page. It is not a conclusion of Coridum; see the Claims that build on it.
