The results showed that the AUC of serum CRP in the predicting intracranial aneurysms was 0.7764 (95% CI: 0.6913–0.8615, P < 0.001), the sensitivity was 93.75% (95% CI: 85.00%–97.54%), the specificity was 71.01% (95% CI: 59.43%–80.38%), and the cutoff value was 15.78 mg/L (Figure 3(c)). The gene discussed is CRP; the disease is Dilatation of the cerebral artery.
