Ing et al developed a new prediction model for diagnosing patients with suspected GCA.[15] Their results are similar to ours in terms of more positive biopsy results in the elderly population as well as more jaw claudication, more ischemic optic neuropathy, and higher platelet levels, ESR, and CRP levels in the positive biopsy group than in the negative biopsy group. This evidence concerns the gene CRP and anterior ischemic optic neuropathy.
