Relationship of serum immunoglobulin-M (IgM) concentration with brachial ankle pulse wave velocity (baPWV) in men (left panel) and women (right panel) by IgM subgroup. Open (men) and closed bars (women) indicate adjusted mean value of baPWV per tertile of IgM. The analysis was adjusted for age, mean arterial pressure, heart rate, body mass index, current smoking (not in women because of small numbers), and alcohol intake, the use of antihypertensive and antihyperglycemic drugs, the presence of hypertension and diabetes, plasma glucose, serum total, and high-density lipoprotein cholesterol. The P-value for trend and the number of subjects per subgroup are given for men and women separately. **P = 0.01 vs. tertile 1
