Plasma levels of cFGF-23 (AUC = 0.844), iFGF-23 (AUC = 0.767), c/i FGF-23 ratio (AUC = 0.724), and PAC (AUC = 0.617) at the time of PA confirmation were predictive of hypertension remission following adrenalectomy, with cFGF-23 level demonstrating superior predictive ability. This evidence concerns the gene FGF23 and Hypertension.
