Effect of beta-carotene daily intake on mean TL in younger (<56 years) and older (>56 years) individuals. Low tertile < 1841 μg/day; mid-tertile: 1841–2863 μg/day; high tertile > 2863 μg/day beta-carotene intake. Correlation of mean TL and beta-carotene daily intake in younger subjects (Pearson coefficient = 0.567, P value = 0.005) and older subjects (Pearson coefficient = 0.168, P value = 0.351).
