Figure 3. Externally-validated nomogram for predicting the risk of cancer-associated VTE.

Figure 3

This nomogram can be used to obtain 6-month VTE risk predictions for outpatients with solid cancers. The unit of D-Dimer is μg/mL. To compute the 6-month VTE risk for an individual patient, D-Dimer (second row) and tumor site category (third row) need to be referred to the point caliper (first row). The obtained points then need to be added, the resulting sum (fourth row) can then be referred to the fifth row to obtain the predicted 6-month risk of VTE.

6monthVTErisk(%) = 100*(1–(1–0.02137053)e(0.6709158)×cancersite+0.2793001×log2(d dimer+1)))
