Quantile plot of estimated Z-score (±SD) of gene-specific DNA methylation and inflammatory pathway in relation to exposure to PM10 six days before withdrawal, depicts a significant association between PM10 quartiles and CD14 methylation gene (P=0.003) and inflammatory pathway (P=0.023) and a significant different slopes of the among genes in relation to exposure to PM10 quartiles the sixth day before withdrawal(P<0.001).
