A scatterplot used to analyze the genetic causal relationship between RA and COPD. In the scatterplot, the x-axis represents the effect of individual SNPs on RA, and the y-axis represents the effect of individual SNPs on COPD. The colored diagonal line represents the fitted line for the causal effect estimation of RA on COPD. From the graph, it can be observed that as the risk of RA increases, the risk of COPD incidence also rises.
