The panels show the 24-hour urinary excretion of tetrahydroaldosterone (A), cortisol (B), total glucocorticoid metabolites (C), and the major adrenal androgen metabolite 11β-hydroxyandrosterone (D) in primary aldosteronism patients (PA; n = 174) in comparison to healthy controls (Co; n = 162), patients with endocrine-inactive adrenal adenoma (EIA; n = 56), patients with subclinical Cushing’s (differentiated into 2 groups: SC1 (n = 55), morning cortisol after 1 mg dexamethasone overnight > 50 and < 138 nmol/l; SC2 (n = 49), morning cortisol >138 nmol/l), and overt adrenal Cushing’s syndrome patients (Cu; n = 47). Boxes represent median and interquartile range, whiskers represent 5th and 95th centiles. **P < 0.01 versus controls, ***P < 0.001 versus controls. Comparisons between groups were made with linear regression models to adjust for age and sex in comparisons between all 6 groups.
