A strong clinical interest in its relationship with venous thromboembolism (VTE), which is a complex trait disease with a heterogeneous annual incidence rate in different countries, has emerged. The relationship between sarcopenia and venous thromboembolism has been reported in observational studies but the causality from sarcopenia to VTE remained unclarified. We aimed to assess the causal effect of sarcopenia on the risk of VTE with the two-sample Mendelian randomization (MR) method.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec002\">\n<jats:title>Methods<\/jats:title>\n<jats:p>Two sets of single-nucleotide polymorphisms (SNPs), derived from two published genome-wide association study (GWAS) meta-analyses and genetically indexing muscle weakness and lean muscle mass separately, were pooled into inverse variance weighted (IVW), weighted median and MR-Egger analyses.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>No evidence was found for the causal effect of genetically predicted muscle weakness (IVW: <jats:italic>OR<\/jats:italic> = 0.90, 95% <jats:italic>CI<\/jats:italic> = 0.76\u20131.06, <jats:italic>p<\/jats:italic> = 0.217), whole body lean mass (IVW: <jats:italic>OR<\/jats:italic> = 1.01, 95% <jats:italic>CI<\/jats:italic> = 0.87\u20131.17, <jats:italic>p<\/jats:italic> = 0.881) and appendicular lean mass (IVW: <jats:italic>OR<\/jats:italic> = 1.13, 95% <jats:italic>CI<\/jats:italic> = 0.82\u20131.57, <jats:italic>p<\/jats:italic> = 0.445) on the risk of VTE.
