Genotypic frequencies of iNOS polymorphisms in cases and controls and their associations with risk of vitiligo.

CI, confidence interval; OR, odds ratio.aThe observed genotype frequencies among the controls were in agreement with the Hardy–Weinberg equilibrium (χ2: P = 0.977 for iNOS-1173 C→T; P = 0.133 for iNOS-954 G→C; P = 0.080 for iNOSEx16+14 C→T).bORs were obtained from a multivariate logistic regression model with adjustment for age and sex.cAdjustment for age and sex.

CI，即置信区间（confidence interval）；OR，即比值比（odds ratio）。a 对照组中观测到的基因型频率符合哈迪-温伯格平衡（Hardy–Weinberg equilibrium）：iNOS-1173 C→T位点的χ²检验P值为0.977，iNOS-954 G→C位点的χ²检验P值为0.133，iNOSEx16+14 C→T位点的χ²检验P值为0.080。b 比值比（OR）通过校正年龄与性别的多因素logistic回归模型计算得到。c 校正年龄与性别。
