  1. Abbreviations: CI, confidence interval; HR, hazard ratio. − denotes no intake of alcohol the last year or no current smoking; + denotes intake of alcohol the last year or current smoking. The HR was estimated through Cox proportional-hazards regression models with corresponding 95% CIs. HR was adjusted for sex and age. Cases/105 years denotes the number of cases in that group (both non-cases and cases) divided by the total amount of person-years/100 000 years.
