Fig. 2From: Replication and expansion of epigenome-wide association literature in a black South African population% Methylation difference between current and never smokers in reference vs. PURE-SA-NW data. Model used for PURE-SA-NW EWAS: methylation ~ smoking + age + cell counts + surrogate variables. Green data points represent CpGs where the 95% CIs for effect size estimates in each sample group overlap. Yellow data points represent CpGs where the 95% CIs for effect size estimates in each sample group do not overlap. Black dashed line: line of equality. Blue dashed line: regression lineBack to article page
