Fig. 3. Marked differences in longitudinal urinary cortisol lability patterns in PTSD patient subgroups participating in an intensive 3-month treatment and research program in the National Center for PTSD. PTSD inpatient subgroups are based on cortisol change from admission to midcourse: sg-A = bottom tercile subgroup with greatest decreases; sg-B = middle tercile subgroup with the least amount of changes; sg-C = top tercile with greatest increases; pilot = pilot study sample involving a much less intensive clinical setting.
