Allele frequency of CXCR1 sequence variants 1 and 2

APN = Acute pyelonephritis; n = number of individuals; N = number of alleles; # nucleotide at position, +217 in the intron. ## nucleotide at position +2608 in the coding sequence. a), b) Fischer's Exact Test, total number of APN prone patients versus total number of controls.

APN即急性肾盂肾炎（Acute pyelonephritis）；n为个体数目；N为等位基因数目。# 内含子区+217位点的核苷酸。## 编码序列+2608位点的核苷酸。a)、b) 采用费希尔精确检验（Fisher's Exact Test），对APN易感患者总人数与对照个体总人数进行比较。
