TSST cortisol response for four groups of impulsive aggressive suicide attempters and non-attempters.
Cortisol values during and after the TSST in the non-attempters, low aggression/low impulsivity attempters, high aggression/low impulsivity attempters, low aggression/high impulsivity attempters, and high aggression/high impulsivity attempters. The curves have been shifted to a common baseline value to illustrate cortisol response to TSST, regardless of baseline level.
