  • a Values for intake are medians for each quintile.

  • b The multivariate models included age (5-year categories), total energy (quintiles), length of follow-up (seven periods), geographic region (Northeast, Midwest, South, California), cigarette smoking (never, past, present smoking of 1–14 cigarettes and≥ 15 cigarettes/day), and height (<62 inches, ≥62 to <64 inches,≥ 64 to <66 inches, ≥66 to <68 inches, or ≥68 inches).

  • c Additional adjustment for quintiles of saturated and trans unsaturated fats.

  • d Q5 95% CI = 95% CIs for quintile 5 RRs.

  • e Ps are two-sided (Wald’s test).
