We will search MEDLINE, EMBASE, Scopus and CINAHL for randomized trials, cohort studies, or case control studies reporting thromboembolic events among adult CHIP carriers and non-carriers in two populations: i) individuals without prior ATE (coronary artery disease, myocardial infarction, ischemic stroke, peripheral arterial disease) or VTE (pulmonary embolism, deep vein thrombosis, superficial vein thrombosis); and ii) individuals with established ATE or VTE. The gene discussed is STUB1; the disease is deep vein thrombosis.
