Table 2.
Correlations and levels of significance of biochemical data in all patients (n=36). Hair cortisol values (measured in pmol/g dry hair weight) were log10-transformed for normality when undergoing statistical analysis. All tests represented lab values from all 36 patients, except for the ACTH values, which excluded one patient due to lack of collection. Diurnal ACTH values (n=35) are not presented, because the r-value for all was ≤0.2 with a p-value ≥0.3.
