BGLAP and adrenal gland hyperfunction: In PA patients BAP (r = 0.53; p = 0.001) and osteocalcin (r = 0.45; p = 0.006) strongly correlated with increasing age, whereas there was no significant correlation of neither bone formation nor bone resorption markers with parameters of hypercortisolism, including DSST, late-night salivary cortisol and 24-h urinary cortisol excretion in univariate analysis (Supplementary Table 1).
