  2. EPIC, European Prospective Investigation into Cancer and Nutrition; LTPAQ, Lifetime Total Physical Activity Questionnaire; ρ, Spearman rank correlation coefficient; CI, confidence interval
  3. a Total non-occupational activity = recreational + household physical activity
  4. b There were no statistically significant differences in correlations for non-occupational activity between subgroups (Pdiff >0.10)
  5. c Vigorous activity was estimated using the sum of time spent in activities with MET values ≥ 6 from each questionnaire
  6. d Light-moderate activity was estimated using the sum of time spent in activities with MET values < 6 from each questionnaire
