Figure 2.

Matrix plot of the correlations between epigenetic variables. The colors represent the degree of pairwise correlation regarding Pearson’s rank correlation coefficient (rho). Blank squares indicate the absence of correlation (p-value > 0.05). Abbreviations: Substance use disorder (SUD); DNAmAge-based epigenetic age acceleration (AAR); Extrinsic epigenetic age acceleration (EEAA); Intrinsic epigenetic age acceleration (IEAA); Hannum-based epigenetic age acceleration (AAHannum); GrimAge-based epigenetic age acceleration (AAGrim); PhenoAge-based epigenetic age acceleration (AAPheno).
