Correlated variants used as initial instrumental variables for supplementary MR analysis.

<p>The variants (<i>r</i>^<i>2</i> < 0.6) are selected from Zhao, et al (PMID: 34140357), which have been reported to be associated with at least one white matter tract (measured by measured by the mean fractional anisotropy, FA) at 5E-8 GWAS significance level. rsID: rsID of the SNP. chr: chromosome. pos: position on hg19. WM: the white matter tract reported to be associated with the SNP in Zhao, et al. <i>P</i>: the GWAS <i>P</i>-value reported in Zhao, et al.</p> <p>(XLSX)</p>
