Associations between prenatal exposure to air pollution and cord blood concentration of IL-1β.

Data is given as the probability of IL-1β being above detection limit per 10 µg/m3 increase of the higher PM10 concentration, for living within 50 m of a major road and for being exposed to indoor air pollutant.1this model was adjusted for gender, gestational weight and maternal smoking during pregnancy.2this model was further adjusted for parental education, maternal atopy and gestational age.3these analyses could not be performed since no subject with detectable IL-1β levels was exposed.
