From: Effect of tobacco smoking on the epigenetic age of human respiratory organs
Comparison of chronological age and epigenetic age acceleration between smokers and non-smokers. Columns correspond to buccal cells (a–c), airway cells (d–f), esophagus tissue (g–i), and lung tissue (j–l). Rows correspond to the chronological age (a, d, g, and j), AccelerationDiff value (b, e, h, and k), and AccelerationResidual value (c, f, i, and l). The latter two measure epigenetic age acceleration. The p value from Kruskal-Wallis tests is written above each sub-figure
