Distribution of VEGF genotypes in B-CLL groups with different mutational status of theIgVH genes.

M: patients with mutated IgVH genes, UM: patients with unmutatedIgVH genes.OR: odds ratio; CI, confidence interval.aHaplotype rs699947/rs833061/rs2010963. X genotype corresponds to n haplotypes other than ACG (CTC or CTG).bThe upper homozygous genotype of each variant is designated the reference with an arbitrary OR value of 1 upon which the OR of the other genotypes are based.Significant risk factors are shown in bold.

M：携带突变型免疫球蛋白重链可变区（IgVH）基因的患者，UM：携带未突变型IgVH基因的患者。OR：比值比（odds ratio）；CI：置信区间（confidence interval）。a. 单倍型rs699947/rs833061/rs2010963：X基因型对应除ACG之外的n种单倍型（CTC或CTG）。b. 将每个变异位点的纯合基因型设为参照组，任意设定其比值比为1，其余基因型的比值比均以此为基准计算。具有统计学意义的危险因素以粗体标注。
