WebSep 14, 2024 · Forest and scatter plots were used to visualize combined results of single and multi-SNP analyses. The scatter plots show the single SNP effects on the exposure against the single SNP effects on the outcome with corresponding standard deviations and estimated regression lines of the multi-SNP analyses. WebTwo-sample MR refers to the approach that the genetic effects of the instruments on the exposure can be estimated in an independent sample other than that used to estimate effects between instruments on the outcome. As more and more GWAS summary statistics become publicly available, the scope of MR also expands with Two-sample MR methods.
