The Association between eGFR and the Aldosterone-to-Renin Ratio and Its Effect on Screening for Primary Aldosteronism

Figure 2

Receiver operating characteristic curves according to eGFR. Evaluation of ARR accuracy for the screening for PA using ROC curve analysis in the full study cohort (a), in those with eGFR < 90 ml/min/1.73 m²  (b), and in those with eGFR ≥ 90 ml/min/1.73 m² (c). ARR: aldosterone-to-renin ratio; eGFR: estimated glomerular filtration rate; PA: primary aldosteronism; ROC: receiver operating characteristic curves.
