FIGURE 2.

Estimated hazard ratios and 95% confidence intervals for lung cancer in relation to intakes of the six foods and nutrients identified in the European Prospective Investigation into Cancer and Nutrition, by smoking status at baseline. Estimates are for a 1 SD increment in intake per day, from Cox proportional hazards models stratified by age at recruitment (<40, 40 to <45, 45 to <50, 50 to <55, 55 to <60, 60 to <65, 65 to <70, 70 to <75, ≥75 years), study centre and sex, and adjusted for number of cigarettes smoked per day (fourths) interacted with smoking status, cigarette smoking years (fourths) interacted with smoking status, body mass index (<20, 20 to <23, 23 to <25, 25 to <30, 30 to <35, ≥35 kg/m²), physical activity (inactive, moderately inactive, moderately active, active), highest level of education (none/primary school, technical/professional school, secondary school, longer education/university), history of diabetes (no, yes) and energy intake (kcal/day, continuous)
