Why the study?
Does a higher sodium to potassium excretion ratio increase the risk of subsequent cardiovascular disease compared to sodium or potassium alone?
Does a higher sodium to potassium excretion ratio increase the risk of subsequent cardiovascular disease compared to sodium or potassium alone?
A higher sodium to potassium excretion ratio is a stronger predictor of subsequent cardiovascular disease risk than either sodium or potassium intake alone.
Supports Na/K ratio for CVD risk assessment over individual electrolytes; extends RCT evidence on electrolyte balance.
A higher sodium to potassium excretion ratio is associated with increased risk of subsequent CVD, with an effect stronger than that of sodium or potassium alone.
