Is the sodium-to-potassium ratio more strongly associated with blood pressure outcomes than either sodium or potassium alone in hypertensive adults?
Is the sodium-to-potassium ratio more strongly associated with blood pressure outcomes than either sodium or potassium alone in hypertensive adults?
The dietary sodium-to-potassium ratio may be a superior metric compared to sodium or potassium alone for evaluating blood pressure outcomes in hypertensive adults.
