Wells Score (DVT)

Wells PS, Anderson DR, Rodger M, et al. Evaluation of D-dimer in the diagnosis of suspected deep-vein thrombosis. This is the modified 10-item Wells DVT model implemented here; it adds "previously documented DVT" (+1) to the original 9-item pretest-probability model (Wells PS et al., The Lancet 1997;350:1795–1798, PMID 9108350).

Goodacre S, Sutton AJ, Sampson FC. Meta-analysis: the value of clinical assessment in the diagnosis of deep venous thrombosis. Pooled analysis showing the Wells score stratifies DVT prevalence across low/moderate/high categories.
