  1. Abbreviations: Ex=former smoker; NSAID=non-steroidal anti-inflammatory drug; BMI=body mass index; OR=odds ratio; CI=confidence interval.
  2. Changes in cancer risk for each of the covariates. These results are for all the studied cancer types grouped together, and hence do not describe differences in exposures between cancer type (see text).
