  • a n = 34.

  • b Brassica vegetable intake measured by 24 HR.

  • c Adjusted for baseline 2:16 only.

  • d Adjusted for baseline 2:16, fiber (g of water-soluble), protein (g), energy (kcal), social approval score.

  • e 2:16, change in 2HE:16HE (intervention-baseline), as measured in 24-h urine samples.

  • f Two-sided trend test using a continuous variable with values representing each category of Brassica intake.
