Note: Boldface indicates statistical significance ^*p ≤ 0.05; ^**p ≤ 0.01; ^***p ≤ 0.001
^a Data are means except where noted
^b 3 categorized as other race
^c Carotenoid index, calculated as the sum of α-carotene, β-carotene,β-cryptoxanthin, and zeaxanthin. Data presented are for nonsmokers and available only through 12 month follow-up visit. A higher index indicates greater fruit and vegetable consumption. Statistical tests performed on log-transformed data
