FIGURE 2.
Multiply adjusted associations between tertiles of 25-hydroxyvitamin D (25-OH-vitamin D) and leukocyte telomere length were stratified by serum C-reactive protein (CRP) concentrations (n = 2160) and adjusted for age, season of vitamin D measurement, menopausal status, use of hormone replacement therapy, and physical activity. High and low CRP concentrations were delineated by a CRP value of 2.0 mg/L. Error bars indicate SE. P value was derived from the nonparametric trend test across all 6 means. There was no significant interaction between CRP and vitamin D.
