ERCC1 and colorectal carcinoma: This meta-analysis showed that ERCC1 rs11615 homozygous CC genotype, but not the heterozygous CT genotype, decreased the risk of CRC, compared with the wild-type TT genotype (CC vs. TT: OR = 0.816, 95% CI = 0.673–0.990, p = 0.039; CT vs. TT: OR = 0.864, 95% CI = 0.711–1.050, p = 0.141) (Figure 2), however, this association was not shown in subgroup analysis of ethnicity and source of control.
