Figure 2. Correlation between transcriptomic age and other epigenetic aging predictors. The scatterplots show the correlation between estimated transcriptomic age and the other epigenetic aging predictors in the study. (A) shows the correlation between Transcriptomic Age and Grim Age, (B) shows the correlation between Transcriptomic Age and Hannum Age, (C) shows the correlation between Transcriptomic Age and Horvath Age, and (D) shows the correlation between Transcriptomic Age and Phenotypic Age. R = Pearson correlation coefficient.
