¹Values are means ± SEs unless indicated otherwise. Labeled means in a column within a group without a common superscript letter are significantly different, P ≤ 0.01. Multiple pairwise t tests were used for comparisons between population groups with df dictated by the NHANES sample design. Na:K, dietary sodium-to-potassium ratio.
