| CABG current/past smokers (n = 72) |
CABG never smokers (n = 82) |

|---|---|---|---|---|
| eNOS 894G > T genotypes | n (%) | 95% CI | n (%) | 95% CI |

| G | 87 (60.4) | 52.3-68.1 | 124 (75.6) | 68.6-81.7 |

*p value = 0.02 for comparison among all eNOS 894G > T genotypes in current/past smoker and never smoker CABG patients.
**p value = 0.01 for comparison between eNOS 894GG and TT genotypes in current/past smoker and never smoker CABG patients.
Genotype and allele frequencies between the two groups were analysed using the chi-square test.
