- aRR/ORs are based on data for male never smokers. Adjustment factors are as in Table 1 except where stated.
- bFor the first three studies, RR (CI) for non-fatal cases have been estimated from those for fatal cases and for combined fatal and non-fatal cases.
- cRR (CI) for the ratio estimated from those for fatal and non-fatal cases.
- dEstimates are for current v non-current snus use, based on non-current smokers.
- eFatal cases are fatal within 28 days of onset.
- fWhereas the results in Table 1 for this study are unadjusted results for non-current smokers comparing current and never snus users, the results in Table 2 are results for non-current smokers comparing ever and never regular snus users with adjustment for hypertension, education, marital status, diabetes, cholesterol and family history of AMI.
- gFixed-effects estimates. There was no evidence of heterogeneity; with p = 0.98 for fatal, p = 0.10 for non-fatal and p = 0.55 for the ratio.
