  1. Notes: R2 represents the total proportion of phenotypic variation that is explained by SNPs in MR analyses. F-statistic denotes the total instrumental strength of the SNPs for each socioeconomic trait. An F-statistic > 10 suggests the strong instrument to explain phenotypic variation
  2. Abbreviations: CI = confidence interval; IVW = inverse-variance weighted; MR = Mendelian randomization; OR = odds ratio; SE = standard error; nSNP = number of single-nucleotide polymorphism; WM = weighted median
