Meta-analysis of the associations between TLR-4 genetic polymorphisms and colorectal cancer risk.

Legend: W - wild allele; M - mutant allele; WW - wild homozygote; WM - heterozygote; MM - mutant homozygote; OR - odds ratio; 95%CI - 95% confidence interval; SNP - single nucleotide polymorphism; PCR-RFLP - polymerase chain reaction-restriction fragment length polymorphism.图例：W代表野生型等位基因（wild allele）；M代表突变型等位基因（mutant allele）；WW代表野生型纯合子（wild homozygote）；WM代表杂合子（heterozygote）；MM代表突变型纯合子（mutant homozygote）；OR代表比值比（odds ratio）；95%CI代表95%置信区间（95% confidence interval）；SNP代表单核苷酸多态性（single nucleotide polymorphism）；PCR-RFLP代表聚合酶链反应-限制性片段长度多态性（polymerase chain reaction-restriction fragment length polymorphism）
