  3. a Data are means except where noted
  4. b 3 categorized as other race
  5. 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
