Correlations and levels of significance of biochemical data in 30 patients with Cushing Syndrome. Hair cortisol values (measured in pmol/g dry hair weight) were log10-transformed for normality when undergoing statistical analysis.

Hair cortisol segment (distance in cm from scalp) Average UFC/BSA over D1+D2 (nmol/24h/m2) Average 17OHS/Cr over D1+D2 (mmol/24h/mol Cr) Midnight serum cortisol (nmol/L) Early morning serum cortisol (nmol/L)
