The study
Setting: tertiary medical centre, USA
124 patients
(aged
?,
?%
male)
referred by primary-care physician with suspected deep
vein thrombosis
Independent unblinded
reference standard, applied in
all
patients from a
non-consecutive appropriate
spectrum.
Reference standard:
Diagnostic test:
Homan's sign: positive if no dorsiflexion of the foot,
on squeezing the calf muscle
- Many patients were excluded on the basis of another diagnosis
confirmed, superficial thrombophlebitis or postphlebitic syndrome
The evidence
pre-test probability of deep vein
thrombosis:
57%,

47% to
66%)
