The heterogeneity was demonstrated to be significant (*P* = 0.007). The OR value for the CC genotype was 0.54 with a 95% CI of 0.32--0.90 and for the TT genotype was 0.57 with a 95% CI of 0.37--0.89. The stratified analysis by ethnicity showed a significant decrease in the overall cancer risk for the CC genotype in a Caucasian population ([Table 4](#T4){ref-type="table"}). In addition, stratified analysis by the source of control did not show any association between the *LEP* rs7799039 genotypes and the risk of colorectal cancer, and the OR values for both Caucasian and Asian populations were consistent with the overall pooled OR. The stratified analysis according to the tumor site was not conducted, because only one study included in our meta-analysis included patients with cancer of the colon and rectum.
