Genotype distributions of RAGE and S100B polymorphisms in donors and recipients of stem cell transplants and healthy controls.

WT – wild-type; SNP – single nucleotide polymorphism. WTRAGE – TT genotype; SNPRAGE – TA + AA genotypes; WTS100B – CC genotype; SNPS100B – CT + TT genotypes.*P values are calculated with the Freeman-Halton extension of the Fisher's exact test for a two-rows by three-columns contingency table.WT 即野生型（wild-type）；SNP 即单核苷酸多态性（single nucleotide polymorphism）。WTRAGE 代表 TT 基因型；SNPRAGE 代表 TA 与 AA 基因型；WTS100B 代表 CC 基因型；SNPS100B 代表 CT 与 TT 基因型。*P 值通过针对 2 行 3 列列联表的费希尔精确检验（Fisher's exact test）弗里曼-霍尔顿（Freeman-Halton）扩展方法计算得到。
