  1. The number in the parenthesis means the number of cancer cases.
  2. Abbreviations: aIR, age adjusted incidence rate; aRR, adjusted relative risk; CI, confidence interval.
  3. a Dietary preference was categorized as meats and vegetables or mixture of vegetables and meat.
  4. bWith the combination of frequency and duration with vigorous, sweat-producing leisure-time physical activity (LPA), it was categorized as (1) low; ≤ 4 times/week for < 30 min/session or ≤ 1 time/week for ≥ 30 min/session, (2) moderate; 2–4 times/week for ≥ 30 min/session or ≥ 5 times/week for < 30 min/session, and (3) high; ≥ 5 times/week for ≥ 30 min/session
  5. c The rate is per 100,000 person-years, adjusted to the age distribution of the entire study population.
  6. dThe multivariate relative risk model using standard Poisson regression analysis adjusted for age, dietary preference, LPA, smoking status, amount of alcohol drinking, body mass index, employment and fasting blood sugar as appropriate.
