Why the study?
Does excessive dietary sodium, limited potassium, or a high sodium-potassium ratio increase the odds of high systolic blood pressure in US adolescents?

No BP association with sodium/potassium intake in adolescents; leaves open independent effects and need for longitudinal data.
Does excessive dietary sodium, limited potassium, or a high sodium-potassium ratio increase the odds of high systolic blood pressure in US adolescents?

Chmielewski et al. (2017) studied this question.
