Finding F-1672

“The crude model analysis revealed that the ORs (95% CIs) for PTB, SGA, and LBW in the group that used an air purifier were 0.92 (0.87, 0.98, p=0.014), 0.94 (0.89, 1.00, p=0.033), and 0.89 (0.85, 0.93, p<0.001), respectively.”

Structure

Outcome: Low birth weight
Intervention: Air purifiers
Setting: home
Study design: cohort study of air purifier use during pregnancy: preterm birth, small-for-gestational-age and low birth weight compared between the mothers who used an air purifier and those who did not, in a crude and in an adjusted model (class 4)
Effect: OR 0.89 (0.85–0.93)
Caveat: the crude model, so it is not adjusted for the household characteristics the study lists
