Figure 2. Association between maternal PM2.5 exposure and SGA status at birth.
A. Maternal PM2.5 exposure from 2 weeks prior to conception until 14 weeks gestation is associated with increased risk of SGA status at birth. B. Among female infants, maternal PM2.5 exposure from 7 weeks to 16 weeks gestation is associated with increased risk of SGA status at birth. C.
