Feasibility of Screening Primary Aldosteronism by Aldosterone-to-Direct Renin Concentration Ratio Derived from Chemiluminescent Immunoassay Measurement: Diagnostic Accuracy and Cutoff Value

<p><i>ROC curves and Bland–Altman plot for ADRR and ARR.</i> (a) This analysis was performed based on the screening test values of ADRR and ARR. Continuous line: ROC curve for ADRR, 0.929 (95% CI: 0.894-0.955); dashed line: ROC curve for ARR, 0.910 (95% CI: 0.873-0.940). P=0.42. (b) There was no significant systematic bias. ADRR: aldosterone-to-direct renin concentration ratio; ARR: aldosterone-to-plasma renin activity ratio; CI: confidence interval.</p>
