Serum potassium < 3.6 mmol/L	2.9 (1.4–5.6)	0.003	1.9 (0.8–4.5)	0.13
ARR baseline ≥ 100 ng/dL/(ng/mL/h)	2.4 (0.6–9.1)	0.22	2.8 (0.4–8.4)	0.49
PAC after SIT ≥ 165 ng/L	4.8 (2.3–10.1)	<0.001	3.1 (1.3–7.4)	0.01

CI—confidence interval; OR—odds ratio; PAC—plasma aldosterone concentration; SIT—saline infusion test.
