The AUC of serum CRP in predicting rupture of intracranial aneurysms was 0.6551 (95% CI: 0.5133–0.7968, P < 0.001), the sensitivity was 90.24% (95% CI: 77.45%–96.14%), the specificity was 42.86% (95% CI: 26.51%–60.93%), and the cutoff value was 60.74 mg/L (Figure 3(d)). This evidence concerns the gene CRP and Dilatation of the cerebral artery.
