Correlation between epigenetic age and chronological age. The figure shows scatter plots of epigenetic age (x-axis) against chronological age (y-axis) in buccal cells (a), airway cells (b), esophagus tissue (c), and lung tissue (d). Blue circles, red triangles, and green inverted triangles indicate non-smokers, smokers, and ex-smokers, respectively. The dashed line is the diagonal where epigenetic age equals to chronological age, the blue solid line is the regression of epigenetic age on chronological age for non-smokers, and the black solid line is the regression of epigenetic age on chronological age for all the smokers and non-smokers
