The study
Setting: university hospital, USA
107 patients
(aged
?,
?%
male)
who had undergone a temporal artery biopsy for giant cell arteritis
Excluded if
insufficient information
Non-independent ?blinded
reference standard, applied in
all
patients from a
consecutive ?appropriate
spectrum.
Reference standard:
- Single temporal artery biopsy. Positive if a positive biopsy or scarring consistent with healed temporal arteritis. If negative, some patients had a contralateral biopsy.
Diagnostic test:
signs and symptoms noted in medical records
The evidence
pre-test probability of giant cell arteritis:
22%,

19% to
26%)
