Bivariate analysis of cancer and patient characteristics on development of VTE. The following comorbid conditions were removed because of prevalences <100: paralysis, cirrhodites, AIDS, and central venous catheter. Myocardial infarction: MI; congestive heart failure: CHF; peripheral vascular disease: PVD; cerebrovascular disease: CVD; chronic obstructive pulmonary disease: COPD.
