CTLA4 genotype frequencies in TB cases stratified for the sizes of opacities in chest radiographs1.

1Analysed by ordinal logistic regression.2Odds ratio.3Confidence interval.4Bonferroni-corrected by the factor of 14 for testing 7 SNPs not in strong linkage disequilibria and two disease phenotypes.

1. 采用有序逻辑回归（ordinal logistic regression）进行分析。
2. 比值比（Odds ratio）。
3. 置信区间（Confidence interval）。
4. 针对7个不存在强连锁不平衡的单核苷酸多态性（SNPs）以及2种疾病表型的检测，采用校正因子为14的邦费罗尼（Bonferroni）校正法。
