Figure 1.

Scatterplot for the correlation between DNA methylation of NR3C1 CpG 12 and heart rate variability (HRV) at reunion 2 episode. HRV is represented by mean respiratory sinus arrhythmia (RSA) values during reunion 2 episodes (Y-axis). The mean percent of DNA methylation of NR3C1 at CpG 12 is shown on the X-axis.
