Association between hypertension and sodium excretion, potassium excretion, and their ratio, among adults aged 20–69 years, NHANES 2014.

	Mid-value of Quartiles of Estimated Usual Excretion
	Q1 (12.5^th percentile) OR, 95% CI	Q2 (37.5^th percentile) OR, 95% CI	Q3 (62.5^th percentile) OR, 95% CI	Q4 (87.5^th percentile) OR, 95% CI

Adjusted for age, sex, race/ethnicity	1.0^†	1.33 (1.08, 1.65)	1.84 (1.17, 2.89)	2.69 (1.29, 5.61)

These rows contain estimated mid-value of quartiles in the population.

^†

indicates p<0.05 and

^‡

indicates p<0.01 for trend across percentiles of estimated usual excretion based on Satterthwaite adjusted F-test.

Fully adjusted models included age, sex, race/ethnicity, education, BMI, history of CVD, diabetes status, chronic kidney disease, smoking status, and physical activity. In addition, models examining sodium excretion simultaneously adjusted for potassium excretion, and vice versa.
