Figure 3.

Boxplots of slope magnitude grouped according to positive (+) or negative (-) ageCGs and CpG context across four tissues. Vertical red and green lines mark the smallest and largest median slope magnitude, respectively, across all four tissues. A significant three-way interaction between CpG context, tissue type, and positive or negative slope trend was found among slope magnitude values (ANOVA on Box-Cox power transformed slope values, P = 5.4 × 10-5).
