Individual MR estimates about the causal effect of plasma vitamin C levels on AD risk in IGAP and UK Biobank GWAS datasets. The x-axis shows the single-nucleotide polymorphism (SNP) effect, and standard error, on plasma vitamin C levels for each of the 11 SNPs, and the y-axis shows the SNP effect and standard error on AD. The regression line for the inverse-variance weighted method is shown. a IGAP AD GWAS dataset; b UK Biobank AD GWAS dataset; c UK Biobank female AD GWAS dataset; d UK Biobank male AD GWAS dataset
