Figure 4

Hair cortisol concentration by selected methodological determinants. (A) Cause of death/capture: mean ± 2 standard deviations (in red) of hair cortisol concentration measured in lumbar guard hair samples. (B) Sample storage: linear regression between measured hair cortisol concentration and time from death/capture to cortisol extraction with the 95% confidence interval as shaded grey area.
