Correlation of cortisol measurements with granulocyte macrophage–colony stimulating factor (GM-CSF) treatment, age, and psychiatric treatment scores. (A) Cortisol levels in placebo- (N = 7) and GM-CSF–treated (N = 9) patients during week 2 of drug or placebo treatment. Horizontal bars indicate the mean, whereas error bars show standard deviation. (B) Correlation between age and cortisol levels during the second week of treatment for acute respiratory distress syndrome (ARDS). (C) Correlations are shown between week 2 blood cortisol levels and 6-month psychiatric symptom scores on the Post-Traumatic Stress Syndrome 10 Questions Inventory (PTSS-10), Impact of Event Scale, Hospital Anxiety and Depression Scale (HADS)-Anxiety, and HADS-Depression.
