ApEn (feedback-sensitive regularity), expressed as ratio of observed to random series, in patients with pituitary-dependent hypercortisolism, patients with primary-adrenal hypercortisolism, and healthy subjects. Patients with unilateral adenoma are represented by triangles and patients with bilateral nodular hyperplasia by diamonds. The P value reflects the difference in mean ApEn ratio between primary-adrenal hypercortisolism and controls. ApEn ratios were similar in the different forms of hypercortisolism.
