Web23 Apr 2024 · Research Synthesis Methods. Mendelian randomization (MR) uses genetic variants as instrumental variables to infer whether a risk factor causally affects a health outcome. Meta‐analysis has been used historically in MR to combine results from separate epidemiological studies, with each study using a small but select group of genetic variants. WebMethodological advances mean that Mendelian randomization can be implemented using summary statistics from GWAS, without individual level data. This requires SNP-exposure associations and SNP-outcome associations obtained from separate datasets and is known as two-sample Mendelian randomization. 这里又有许多术语需要给大家做做 ...
