Finding F-1673

“And CRP level of the subjects was significantly reduced by 20.93% (95%CI: 6.56%, 33.10%), 23.44% (95%CI: 2.77%, 39.39%) and 24.11% (95%CI: 4.21%, 39.69%) for each PM2.5 exposure IQR decrease, on lag1, lag01, and lag02”

Structure

Factor: Particulate matter (PM₂.₅ and PM₁₀)
Intervention: Air purifiers
Setting: home
Study design: double-blind crossover trial in patients with stable coronary heart disease: real against sham portable air purifiers in the bedroom, with personal fine particle exposure measured and inflammation and coagulation markers taken at several lags (class 2)
Effect: difference 20.93 (6.56–33.10) per 1 IQR %
Caveat: the outcome is C-reactive protein, which has no slug in the Vocabulary; the exposure step is one interquartile range of personal fine particle exposure, which the study puts at 22.51 µg/m3, and the value here is for lag1
