From: Effect of tobacco smoking on the epigenetic age of human respiratory organs
Comparison of epigenetic age acceleration between smokers and non-smokers grouped by gender. Comparison of epigenetic age acceleration of airway cells (a, b) and lung tissue (c, d) between smokers and non-smokers, grouped by gender (males, a and c) and (females, b and d). e A forest plot generated by the meta-analysis on the gender effect on epigenetic age-acceleration of lung tissue in smokers. Each row in the forest plot shows the mean difference in epigenetic age acceleration between males and females in smokers’ lung tissue and the 95% confidence interval
