Finding F-0696

“The frequency of airing the home in winter (by opening doors or windows) was the strongest predictor of NO2 with an estimated mean increase of 0.018 ppm (95% CI: 0.018, 0.028; p ≤ 0.001) observed when the residence was opened daily, compared to infrequently or never.”

Structure

Factor
Nitrogen dioxide (NO₂)
Intervention
Natural ventilation
Setting
dwelling, AU
Study design
cross-sectional measurement study in 111 non-smoking residences in Perth, Western Australia: 24-hour indoor measurement of particulate matter, total volatile organic compounds, carbon dioxide, carbon monoxide, nitrogen dioxide and formaldehyde with a direct-reading monitor, set against building and household characteristics taken from a questionnaire (class 4)
Effect
beta 0.018 (0.018–0.028)
Sample
111 homes
Flags
implausible
Caveat
the printed interval starts at the point estimate (0.018 (0.018, 0.028)), the same in the text and in Table 6, so the lower bound is probably a misprint; the estimate is taken as printed
