Relative risk of upper aerodigestive cancers by alcohol intake and smoking status

* Relative risk and 95% g-s confidence intervals (CI) by amount of alcohol consumed and smoking compared to consumption of 1-2 drinks/week in never smokers (relative risk=1.0), adjusted for region, body mass index, deprivation index, educational attainment, strenuous exercise, use of oral contraceptives and menopausal hormones and stratified by year of birth and year completed recruitment questionnaire. The relative risks are for categories of one to two, three to six, seven-14, ≥ 15 drinks/week at recruitment plotted against the remeasured averages 7.8 years later in each of these categories (never smokers 2.5, 5.3, 9.6, 16.3 drinks/week respectively; past smokers 2.9, 5.8, 10.4, 17.2 drinks/week respectively; current smokers < 10 cigarettes/day 3.0, 6.0, 10.6, 17.6 drinks/week respectively; current smokers ≥ 10 cigarettes/day 2.7, 5.8, 10.6, 17.9 respectively). † Includes oesophageal squamous cell carcinoma, oral cavity and pharynx and larynx cancers
