List of statements that did not achieve consensus and their outcomes

NoStatementAgreementOutcome
5If the patient has undergone ultrasound of the temporal artery/ies then a summary of the radiological findings can be helpful if provided on the request form62%Retain
7The corticosteroid therapy dose taken at the time of biopsy should be recorded on the request form50%Discard
8The clinician who performs the temporal artery biopsy should record the length of the biopsy (prefixation)38%Discard
10It is recommended to comment on the presence of any tortuosity at the time of cut-up25%Discard
17After examining deeper levels, if the pathologist still feels that the tissue has not been adequately examined, then exhausting the block can be considered before definitively calling a biopsy negative for GCA58%Discard
33The presence or absence of oedema should be reported42%Discard
36It is useful to comment on the presence or absence of neoangiogenesis33%Add to research agenda
37If present, the location of neoangiogenesis within the artery wall should be specified in the report20%Discard
45I find the terms ‘healed’ or ‘treated’ arteritis are unhelpful for clinicians38%Discard -combined with statement 44
46In the short term (defined as<1 month), corticosteroid therapy at full doses does not seem to influence the histological findings42%Add to research agenda
47In cases where the histology findings are uncertain, it is best practice to discuss these cases in an MDT setting69%Discard
63Refers to WSI number 4—I would report this as temporal (giant) cell arteritis without specifying the pattern type64%Add to research agenda
66Refers to WSI number 5—I would report this as temporal (giant) cell arteritis without specifying the pattern type55%Discard
71In some, but not all, of these sections there is focal periarteriolar lymphocytic infiltrate in the adventitial blood vessels40%Discard
73There is no evidence of neoangiogenesis50%Discard
75I would request for an EVG to look for the extent of disruption in the elastin layer before considering my differentials (atherosclerosis related changes)36%Add as research agenda
Additional statements added by the expert participants
82It is preferable that in cases where there are isolated aggregates of chronic inflammatory cells seen around the small vessels surrounding a main vessel; these should be discussed at a CPC meeting or equivalent55%Discard
