Inverse correlations between urinary K excretion and dyslipidemic risk in Japanese adolescent girls. The participants who had successfully collected 24-h urine were divided into higher (n = 105) and lower (n = 107) groups at a median of urinary K excretion. (A) Serum triglyceride level and (B) Serum HDL level were measured in higher and lower urinary K excretion groups. Values are expressed as means ± SE. *P < 0.05, **P < 0.005.
