KIR genes and alleles identified in individuals with mild, severe and critical COVID-19.

The statistical significance of the comparisons between the frequencies of KIR genes and alleles in the groups of individuals with severe and critical COVID-19 and the group of individuals with mild COVID-19 was calculated using Fisher’s exact test 2x2. Significance levels were corrected by Bonferroni correction.

针对重症及危重型新型冠状病毒肺炎（COVID-19）患者组与轻症新型冠状病毒肺炎患者组中杀伤细胞免疫球蛋白样受体（KIR）基因及等位基因的频率差异开展组间比较，其统计学显著性采用2×2 Fisher确切概率法进行计算，并通过Bonferroni校正法对显著性水平予以校正。
