Predicting Venous Thromboembolic Events in Patients with Coronavirus Disease 2019 Requiring Hospitalization: an Observational Retrospective Study by the COVIDIC Initiative in a Swiss University Hospital

Table 4

Performance of different combinations of D-dimer values and Wells score for PE in predicting VTE upon admission.

	Sensitivity (%)	Specificity (%)	PPV (%)	NPV (%)	Accuracy
D-dimer	71.4	87.9	99.0	87.4	0.797
Wells score for	71.4	77.4	9.3	98.8	0.772
Wells score for and D-dimer	57.1	91.6	18.2	98.5	0.905
Wells score for points or D-dimer value	92.9	46.9	5.4	99.5	0.483

PPV: positive predictive value; NPV: negative predictive value.
