From: Genetic and epigenetic susceptibility of airway inflammation to PM2.5 in school children: new insights from quantile regression

Fig. 2

Empirical log-FeNO distribution among children without copy of the haplotype (black line) and its associated predicted distribution among children with two copies of haplotype, 10 μg/m3 increases in short-term PM2.5 exposure and 10% decreases in methylation level (Red line). Panel a) shows the density curves of both distributions and selected percentiles (10%, 30%, 50%, 70% and 90%), respectively. Panel b) is a QQ plot and plotted the quantiles of predicted distribution against those of empirical distribution
