Log-transformed cortisol trajectories. The y-axis refers to predicted
cortisol level. Low and high depressive symptom groups were created using a
cutpoint of 10 on the time-varying CES-D (CES-D at each assessment was used to
create groups for that assessment) and are presented for graphical purposes
only. The following variables were controls in all analyses: chemotherapy and
radiation therapy, estrogen and progesterone receptor status, time from surgery
to baseline, age, income, and study arm (intervention vs. assessment only).
Sample sizes for the groups at each timepoint were as follows: baseline not
depressed n=182, baseline depressed n=45; 4 months not depressed n=170, 4 months
depressed n=27; 8 months not depressed n=171, 8 months depressed n=22; 12 months
not depressed n=164, 12 months depressed n=20. CES-D=Center for Epidemiological
Studies Depression Scale.
