  • Data are means ± SD, ranges, or n unless otherwise indicated.

  • * P values are for test of equality between indicated background characteristics.

  • P values are for test of trend over nutrient-intakes tertiles. Tests for changes in costs are adjusted for baseline costs. Values in bold indicate statistical significance.
