A PCA loading plot showing the distribution of maternal inflammatory proteins at pregnancy week 24 from a principal component analysis in the COPSAC2010 cohort. B PCA score plots of the maternal inflammatory proteomic profile at pregnancy week 24 showing patterns of correlation from linear regression models between proteins and the distribution of mothers with high vs low (median split) ambient air pollution exposure for PM2.5, PM10, and NO2.
