Figure 4.

Plasma and urine content of advanced glycation end products (AGE) (a, b) and advanced oxidation protein products (AOPP) (d, e), as well as plasma/urine index of the AGE (c) and AOPP (f) content of the controls, incidentaloma, pheochromocytoma, and Cushing's/Conn's adenoma patients. Results are presented as with minimum and maximum. ^∗p < 0.05, ^∗∗p < 0.01, ^∗∗∗p < 0.001, and ^∗∗∗∗p < 0.0001 indicate significant differences from the controls; ^p < 0.05 indicates significant differences from the pheochromocytoma group.
