Potential marker genes for chronic obstructive pulmonary disease revealed based on single-cell sequencing and Mendelian randomization analysis
Figure 2. Mendelian randomization analysis between key genes and COPD. (A–D) Genes represented were CD14, CSTA, COTL1, and GZMH, respectively. Different colors indicated different statistical methods, and the slopes of the lines denoted the causal effect of each method, respectively.
