  1. a In the Rolandsson 2005 [20] study, snuff use was compared with snuff non-use; in the Bergström 2006 [11] study, current or former use was compared with never use; in the Hirsch 1991 [9] study, snuff use was compared with no tobacco use
  2. b All statistical tests are unadjusted for any potential confounding variable. Where necessary ORs and 95% CIs are calculated from the data provided in the source paper
