In a univariate logistic regression, KRAS mutational status was correlated with an increased risk of thrombosis, with an odds ratio (OR) of 2.758 (95% CI: 1.552–4.903, p = 0.001) for the general outcome of VTE, while the OR for DVT was 3.125 (95% CI: 2.537–5.039, p = 0.002) and for PE was 1.752 (95% CI: 1.239–3.756, p = 0.045). This evidence concerns the gene KRAS and deep vein thrombosis.
