Accelerated epigenetic age as a biomarker of cardiovascular sensitivity to traffic-related air pollution
Figure 2. Association between residential proximity to roadways and PAD by AAD tertiles Interaction between AAD and residential proximity to roadways is visualized by associating residential proximity to roadways in the first tertile of the AAD distribution and comparing association to those seen for the third tertile of the AAD distribution. AAD = age acceleration difference, PAD = peripheral arterial disease.
