Heatmap of perceived stress scale (PSS), inflammatory markers and BDNF DNA methylation with differentially methylated CpGs.

Data showed in z-score. Perceived stress scale (PSS), BDNF DNA methylation and inflammatory markers were scaled from −4 to 4, with red indicating high levels of inflammatory cytokines or high methylation or perceived stress, while blue low levels of inflammatory cytokines or low methylation or low perceived stress.
