Mean normalized ratio ng target to geometric mean of ng reference genes.

Standard deviation.

H = chronic exposure to severe life events and difficulties.

L = no chronic exposure to severe life events and difficulties.

P from two-sided t-test of differential gene expression (H–L strata).

Ratio of mean H/mean L.
