From: Prophylactic anticoagulation to prevent venous thromboembolism in traumatic intracranial hemorrhage: a decision analysis

Figure 5

Sensitivity analysis on effectiveness of low molecular weight heparin at preventing deep venous thrombosis. One-way sensitivity analysis in which the relative effectiveness of low molecular weight heparin (LMWH) at preventing deep vein thrombosis (DVT) is varied (small green diamonds). The two strategies (LMWH versus no prophylaxis) are seen to have equivalent expected values (utilities) at the point (threshold value) where the two lines intersect. This analysis suggests that providing LMWH at 24 hours after traumatic brain injury with intracranial hemorrhage would become the preferred strategy only if it was more than 80% effective at preventing DVT.
