Relationship of Hair Cortisol Concentration With Perceived and Somatic Stress Indices: Cross-Sectional Pilot Study

Exponentiation, based on the variable form, of the β-coefficient with 95% CIs and t values were calculated. We performed sensitivity analyses for the variables in our models to determine the minimum effect size that could yield a statistically significant result with a significance level of 0.05 and power of 0.80 for our sample size using Cohen f2 measures. All study variables were available for all study participants; thus, we had no missing data to exclude.
