This study has several advantages over previous studies; with our large sample size, we were able to adjust for a large number of covariates. This provides a more accurate estimate of the risk of a positive D-dimer, even for factors previously known to be associated with positive results. In addition, we were able to identify several factors not previously known to be associated with positive D-dimer results and describe the association of subcategories of malignancy, surgery, connective tissue disease, lung disease, and pregnancy
