The intraindividual coefficient of variation (a measure of within person variance) was 25.5% for sodium, 22.4% for potassium, and 22.8% for sodium-to-potassium ratio. The inter-individual coefficient of variation (a measure of between person variance) was 46.5% for sodium, 41.0% for potassium, and 41.8% for sodium-to-potassium ratio.

^a95% confidence intervals do not overlap and usual nutrient intake is statistically significantly different compared with the reference category.
