Table II.

Comparison between genotypes, odds ratio and p value showed that genotype ERCC1 AA was the most important risk factor in our population; AA odds ratio: 3.333, 95% CI: 1.917-5.795, p = 0.001; GG odds ratio: 0.692, 95% CI: 0.4-1.199, p = 0.188; AG odds ratio: 0.208, 95% CI: 0.124- 0.348, p = 0.342. After genotype ERCC1 AA, genotype GG was the most important risk factor in our population

Genotype ERCC1	Odds ratio	95% confidence interval	Value of p
AG	0.208	0.124-0.348	0.342
GG	0.692	0.4-1.199	0.188
AA	3.333	1.917-5.795	0.001
