Patients with unilateral PA showed a significantly lower estimated glomerular filtration rate compared with patients with bilateral disease (P &amp;lt; .05). The cohorts differed significantly in potassium supplementation, serum potassium, baseline and post-saline plasma aldosterone, baseline aldosterone to renin ratio, and adenoma in imaging. The proposed prediction score had a sensitivity of 46% (58 of 127) and a specificity of 80% (53 of 66). In patients below 40 years (n = 28), the prediction score achieved a specificity of 100%; however, relying only on imaging in this young cohort, the specificity dropped to 83%.<\/jats:p>\n
