Fig. 1. Illustration of computations of mean salivary cortisol level and slope of diurnal change in cortisol using log-transformed cortisol values. Top, Values for raw salivary cortisol for each time point across the 3 days of sampling. Bottom, Log-transformed cortisol values. Mean cortisol level was assessed by summing across all 12 points and computing a mean; line represents diurnal variability or slope of the diurnal curve, calculated by regressing cortisol values on the time of day collected.

Fig. 3. Diurnal mean cortisol levels were higher among patients who reported less appraisal, belonging, and tangible support. Bars show mean (and SEM) raw salivary cortisol levels of patients split at the median of each subscale.
