Note. Gender (female=0; male=1); Smoker (0=non-smoker; 1=smoker); Cort. Medication (0=no corticosteroid medication use; 1=corticosteroid medication use); Other Medication (0=no other medication use; 1=other medication use). Means for dichotomous variables can be interpreted as proportions (e.g., 42 percent male). Original units for cortisol are nmol/liter. A log transformed cortisol value (x) can be converted back to the original scale using the following formula: e^x − 1.
