Finding F-0198

“For example, a 10 μg/m3 increase of 7-day (lag 06) average concentrations of PM10 (particulate matter no greater than 10 microns), SO2 , NO2 was associated with 0.81% (95% confidence intervals (CI) 0.39%, 1.22%), 2.22% (95% CI: 1.27%, 3.16%) and 2.31% (95% CI: 1.17%, 3.45%) increase in outpatient visits for eczema, respectively.”

Structure

Factor: Nitrogen dioxide (NO₂)
Outcome: Dermatitis
Population: dermatology outpatients
Setting: city (ambient), CN
Study design: time-series analysis of daily outpatient visits for eczema at a dermatology department in Shanghai against ambient air pollutants and meteorological factors, generalized additive models with single-day and cumulative lags (class 4)
Effect: difference 2.31 (1.17–3.45) per 10 %
Averaging time: 7-day moving average (lag 0-6)
Caveat: outcome is outpatient visits for eczema, filed under dermatitis
