Integration of SNP Disease Association, eQTL, and Enrichment Analyses to Identify Risk SNPs and Susceptibility Genes in Chronic Obstructive Pulmonary Disease

Figure 4

Boxplot of expression levels of four susceptibility genes. Four groups of samples were used for differential analysis in each gene (i.e., DYNC1H1, COL6A5, CR1, and TNFAIP3), and the boxplot with similar colors indicates that each sample type is internally divided into two groups. The significant difference is measured according to value (, ).
