Recommended approach for the use of ARR in the screening for PA. The protocol was interpreted as follows. Firstly, we enrolled subjects in accordance with the inclusion criteria and exclusion criteria. Then confirmation tests were conducted in every hypertension case with PAC higher than 10 ng/dl to fully ensure no PA cases were missed, regardless of the ARR value. Finally, PA was carefully diagnosed in cases with positive confirmation test results and clinical outcomes.
