Insights on “Optimizing” Sample Size in Salivary Bioscience Research-Supplemental Figures
Drop Date: June 2023 Each graph portrays the distribution of salivary Coritsol Awakening Response, Cortisol Diurnal, and Trier Social Stress Test, searched from PubMed, based on the number of participants involved in each study. You’ll notice the distributions are non-normal and for this reason, we draw the reader’s attention to the median as the measure [...]
Insights on “Optimizing” Sample Size in Salivary Bioscience Research
Drop Date: June 2023 By Douglas A. Granger and Kristina Feghali Insights on “Optimizing” Sample Size in Salivary Bioscience Research In the biobehavioral sciences, one of the most challenging issues is estimating statistical power. The underlying question is: "Does the study design include enough participants to rule out the possibility that observations made would be [...]

DHEA & DHEA(S) – The Stress Whisperers
Drop Date: October 2021 In This Drop: DHEA & DHEA(S) - The Stress Whisperers DHEA and cortisol are both hormones produced by the adrenal glands. While DHEA and cortisol are often measured independently as biomarkers, measuring the two hormones together can offer advanced insights for continued stress research. As salivary cortisol becomes more widespread, researchers [...]
