  • a n = 34.

  • b Median Brassica or IGS intake within each category.

  • c Derived from 24 HRs.

  • d Estimated IGSL intake calculated from published estimates and self-reported Brassica consumption.

  • e Crude: Adjusted for baseline 2:16 only.

  • f Adjusted: mean 2:16 values and differences in 2:16 adjusted for energy (kcal), protein (g), fiber (g), and social approval scores.

  • g Two-sided P under null hypothesis that the difference equals 0.
