Figure 1. Change of radial bone mineral density by tertiles of serum carotenoids in post-menopausal female subjects.

Multivariate-adjusted means of radial bone mineral density were calculated after adjusting for age, weight, height, years since menopause, current tobacco use, regular alcohol intake, exercise habits, supplement use, and total energy intake. P-values over the quartiles of serum carotenoids were assessed with a test for linear trends using linear regression.
